| CVE-2026-53242 | In the Linux kernel, the following vulnerability has been resolved: ALSA: PCM: Fix wait queue list corruption in snd_pcm_drain() on linked streams snd_pcm_drain() uses init_waitqueue_entry which does not clear entry.prev/next, and add_wait_queue with a conditional remove_wait_queue that is skipped when to_check is no longer in the group after concurrent UNLINK. The orphaned wait entry remains on the unlinked substream sleep queue. On the next drain iteration, add_wait_queue adds the entry to | 416baaa9-dc9f-4396-8d5f-8c081fb06d67 | 7.8 | 0.14% | 2026-06-25 | 2026-06-30 |
| CVE-2026-53241 | In the Linux kernel, the following vulnerability has been resolved: ALSA: seq: dummy: fix UMP event stack overread The dummy sequencer port forwards events by copying an incoming struct snd_seq_event into a stack temporary, rewriting source and destination, and dispatching the temporary to subscribers. That legacy event storage is smaller than struct snd_seq_ump_event. When a UMP event reaches the dummy client, the copy leaves the UMP flag set but only provides legacy-sized stack storage.

| CVE-2026-53240 | In the Linux kernel, the following vulnerability has been resolved: xfrm: iptfs: fix use-after-free on first_skb in __input_process_payload __input_process_payload() stores first_skb into xtfs->ra_newskb under drop_lock when starting partial reassembly, then unlocks and breaks out of the processing loop. The post-loop check reads xtfs->ra_newskb without the lock to decide whether first_skb is still owned: if (first_skb && first_iplen && !defer && first_skb != xtfs->ra_newskb) Between spi | 416baaa9-dc9f-4396-8d5f-8c081fb06d67 | 8.8 | 0.42% | 2026-06-25 | 2026-06-30 |
| CVE-2026-53239 | In the Linux kernel, the following vulnerability has been resolved: xfrm: policy: fix use-after-free on inexact bin in xfrm_policy_bysel_ctx() Fix the race by pruning the bin while still holding xfrm_policy_lock, before dropping it. Use __xfrm_policy_inexact_prune_bin() directly since the lock is already held. The wrapper xfrm_policy_inexact_prune_bin() becomes unused and is removed.

| CVE-2026-53238 | In the Linux kernel, the following vulnerability has been resolved: netlabel: validate unlabeled address and mask attribute lengths netlbl_unlabel_addrinfo_get() used the address attribute length to determine whether the attribute data could be read as an IPv4 or IPv6 address, but did not independently validate the corresponding mask attribute length. A crafted Generic Netlink request could therefore provide a valid IPv4/IPv6 address attribute with a shorter mask attribute, which would later | 416baaa9-dc9f-4396-8d5f-8c081fb06d67 | — | 0.18% | 2026-06-25 | 2026-06-30 |
| CVE-2026-53237 | In the Linux kernel, the following vulnerability has been resolved: gpio: mvebu: fix NULL pointer dereference in suspend/resume mvebu_pwm_suspend() and mvebu_pwm_resume() are called for all GPIO banks during suspend/resume, but not all banks have PWM functionality. GPIO banks without PWM have mvchip->mvpwm set to NULL. Calling mvebu_pwm_suspend() with mvpwm == NULL causes a NULL pointer dereference when it tries to access mvpwm->blink_select.

| CVE-2026-53236 | In the Linux kernel, the following vulnerability has been resolved: tcp: restrict SO_ATTACH_FILTER to priv users This patch restricts the use of SO_ATTACH_FILTER (cBPF) on TCP sockets to users with CAP_NET_ADMIN capability. This blocks potential side-channel attack where an unprivileged application attaches a filter to leak TCP sequence/acknowledgment numbers. | 416baaa9-dc9f-4396-8d5f-8c081fb06d67 | — | 0.18% | 2026-06-25 | 2026-06-30 |
| CVE-2026-53235 | In the Linux kernel, the following vulnerability has been resolved: net: add pskb_may_pull() to skb_gro_receive_list() skb_gro_receive_list() calls skb_pull(skb, skb_gro_offset(skb)) without first ensuring the data is in the linear area via pskb_may_pull(). When the skb arrives via napi_gro_frags(), skb_headlen can be 0 (all data in page fragments) while skb_gro_offset is non-zero (after IP+TCP header parsing). The skb_pull() then decrements skb->len by skb_gro_offset but skb->data_len stays u | 416baaa9-dc9f-4396-8d5f-8c081fb06d67 | 7.5 | 0.47% | 2026-06-25 | 2026-06-30 |
| CVE-2026-53234 | In the Linux kernel, the following vulnerability has been resolved: net: ibm: emac: Fix use-after-free during device removal The driver was using devm_register_netdev() which causes unregister_netdev() to be deferred until the devres cleanup phase, which runs after emac_remove() returns. This creates a use-after-free window where: 1. emac_remove() is called, which tears down hardware (cancels work, detaches modules, unregisters from MAL) 2. emac_remove() returns 3. devres cleanup runs and | 416baaa9-dc9f-4396-8d5f-8c081fb06d67 | — | 0.18% | 2026-06-25 | 2026-06-30 |
| CVE-2026-53233 | In the Linux kernel, the following vulnerability has been resolved: netdev: fix double-free in netdev_nl_bind_rx_doit() Sashiko flags that genlmsg_reply() always consumes the skb. The error path calls nlmsg_free(rsp) so we can't jump directly to it. Let's not unbind, just propagate the error to the user. This is the typical way of handling genlmsg_reply() failures. They shouldn't happen unless user does something silly like calling the kernel with an already-full rcvbuf. | 416baaa9-dc9f-4396-8d5f-8c081fb06d67 | — | 0.18% | 2026-06-25 | 2026-06-30 |
| CVE-2026-53232 | In the Linux kernel, the following vulnerability has been resolved: net: phy: clean the sfp upstream if phy probing fails Sashiko reported that we don't call sfp_bus_del_upstream() in the probe failure path, so let's add it, otherwise the sfp-bus is left with a dangling 'upstream' field, that may be used later on during SFP events. This issue existed before the generic phylib sfp support, back when drivers were calling phy_sfp_probe themselves. | 416baaa9-dc9f-4396-8d5f-8c081fb06d67 | 8.8 | 0.16% | 2026-06-25 | 2026-06-30 |
| CVE-2026-53231 | In the Linux kernel, the following vulnerability has been resolved: net: phy: don't try to setup PHY-driven SFP cages when using genphy We don't have support for PHY-driver SFP cages with the genphy code. On top of that, it was found by sashiko that running sfp_bus_add_upstream() for genphy deadlocks, as for genphy the PHY probing runs under RTNL, which isn't the case for non-genphy drivers. This problem was reproduced, and does lead to a deadlock on RTNL. Before the blamed commit, the phy_ | 416baaa9-dc9f-4396-8d5f-8c081fb06d67 | 5.5 | 0.09% | 2026-06-25 | 2026-07-02 |
| CVE-2026-53230 | In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Fix slab-out-of-bounds in mlx5_query_nic_vport_mac_list mlx5_query_nic_vport_mac_list() sizes its firmware command buffer using the PF's log_max_current_uc/mc_list capabilities. When querying a VF vport with a larger configured max (via devlink), the firmware response can overflow this buffer: BUG: KASAN: slab-out-of-bounds in mlx5_query_nic_vport_mac_list+0x453/0x4c0 [mlx5_core] Read of size 4 at addr ff1100013ff | 416baaa9-dc9f-4396-8d5f-8c081fb06d67 | 8.7 | 0.13% | 2026-06-25 | 2026-07-02 |
| CVE-2026-53229 | In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: xsk: Fix DMA and xdp_frame leak on XDP_TX xmit failure In the XSK branch of mlx5e_xmit_xdp_buff(), when sq->xmit_xdp_frame() returns false (e.g. XDPSQ is full), the function returns without unmapping the DMA address or freeing the xdp_frame allocated by xdp_convert_zc_to_xdp_frame(). The xdpi_fifo push only happens on success, so the completion path cannot recover these entries.

| CVE-2026-53228 | In the Linux kernel, the following vulnerability has been resolved: ipv6: sit: reload inner IPv6 header after GSO offloads ipip6_tunnel_xmit() caches the inner IPv6 header pointer at function entry and continues using it after iptunnel_handle_offloads(). For GSO skbs, iptunnel_handle_offloads() calls skb_header_unclone(). When the skb header is cloned, skb_header_unclone() can call pskb_expand_head(), which may move the skb head. The pskb_expand_head() contract requires pointers into the skb | 416baaa9-dc9f-4396-8d5f-8c081fb06d67 | 9.8 | 0.56% | 2026-06-25 | 2026-07-02 |
| CVE-2026-53227 | In the Linux kernel, the following vulnerability has been resolved: net: openvswitch: fix possible kfree_skb of ERR_PTR After the patch in the "Fixes" tag, the allocation of the "reply" skb can happen either before or after locking the ovs_mutex. However, error cleanups still follow the classical reversed order, assuming "reply" is allocated before locking: it is freed after unlocking. If "reply" allocation happens after locking the mutex and it fails, "reply" is left with an ERR_PTR, and ex | 416baaa9-dc9f-4396-8d5f-8c081fb06d67 | 5.5 | 0.14% | 2026-06-25 | 2026-07-02 |
| CVE-2026-53226 | In the Linux kernel, the following vulnerability has been resolved: gpio: rockchip: fix generic IRQ chip leak on remove The driver allocates domain generic chips using irq_alloc_domain_generic_chips() during probe. However, on driver remove/teardown, the generic chips are not automatically freed when the IRQ domain is removed because the domain flags do not include IRQ_DOMAIN_FLAG_DESTROY_GC. This causes both the domain generic chips structure and the associated generic chips to be leaked. Ad | 416baaa9-dc9f-4396-8d5f-8c081fb06d67 | 5.5 | 0.12% | 2026-06-25 | 2026-07-02 |
| CVE-2026-53225 | In the Linux kernel, the following vulnerability has been resolved: sctp: fix uninit-value in __sctp_rcv_asconf_lookup() __sctp_rcv_asconf_lookup() in net/sctp/input.c only checks that the ASCONF chunk can hold the ADDIP header and a parameter header, then calls af->from_addr_param(), which reads the full address (16 bytes for IPv6) trusting the parameter's declared length. An unauthenticated peer can send a truncated trailing ASCONF chunk that declares an IPv6 address parameter but stops aft | 416baaa9-dc9f-4396-8d5f-8c081fb06d67 | 9.1 | 0.54% | 2026-06-25 | 2026-07-02 |
| CVE-2026-53224 | In the Linux kernel, the following vulnerability has been resolved: sctp: validate embedded INIT chunk and address list lengths in cookie sctp_unpack_cookie() only checked that the embedded INIT chunk length did not exceed the remaining cookie payload, but did not ensure that the INIT chunk is large enough to contain a complete INIT header. A malformed COOKIE_ECHO can therefore carry a truncated INIT chunk whose length field is smaller than sizeof(struct sctp_init_chunk).

| CVE-2026-53223 | In the Linux kernel, the following vulnerability has been resolved: net: guard timestamp cmsgs to real error queue skbs skb_is_err_queue() treats PACKET_OUTGOING as the sole marker for an skb from sk_error_queue. That assumption is not true for AF_PACKET sockets: outgoing packet taps are also delivered to packet sockets with skb->pkt_type == PACKET_OUTGOING, but their skb->cb is owned by AF_PACKET instead of struct sock_exterr_skb. If such an skb is received with timestamping enabled, the gen | 416baaa9-dc9f-4396-8d5f-8c081fb06d67 | 7.1 | 0.13% | 2026-06-25 | 2026-07-02 |
