In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: add a check on the tid coming from the firmware ba_notif->tid is a firmware-controlled u8 that is used directly as an array index into tid_data[] without any validation. Add a bounds check against IWL_MAX_TID_COUNT before dereferencing the array.

An update of the linux package has been released.

  - In the Linux kernel, the following vulnerability has been resolved: crypto: essiv - Handle EBUSY correctly     As it is essiv only handles the special return value of EINPROGERSS, which means that in all other cases     it will free data related to the request. However, as the caller of essiv may specify MAY_BACKLOG, we also     need to expect EBUSY and treat it in the same way. Otherwise backlogged requests will trigger a use-after-     free.

  - In the Linux kernel, the following vulnerability has been resolved: net: avoid potential underflow in     qdisc_pkt_len_init() with UFO After commit 7c6d2ecbda83 (net: be more gentle about silly gso requests     coming from user) virtio_net_hdr_to_skb() had sanity check to detect malicious attempts from user space     to cook a bad GSO packet. Then commit cf9acc90c80ec (net: virtio_net_hdr_to_skb: count transport header     in UFO) while fixing one issue, allowed user space to cook a GSO packet with the following characteristic     : IPv4 SKB_GSO_UDP, gso_size=3, skb->len = 28. When this packet arrives in qdisc_pkt_len_init(), we end up     with hdr_len = 28 (IPv4 header + UDP header), matching skb->len Then the following sets gso_segs to 0 :
    gso_segs = DIV_ROUND_UP(skb->len - hdr_len, shinfo->gso_size); Then later we set     qdisc_skb_cb(skb)->pkt_len to back to zero :/ qdisc_skb_cb(skb)->pkt_len += (gso_segs - 1) * hdr_len; This     leads to the following crash in fq_codel [1] qdisc_pkt_len_init() is best effort, we only want an     estimation of the bytes sent on the wire, not crashing the kernel. This patch is fixing this particular     issue, a following one adds more sanity checks for another potential bug.

  - In the Linux kernel, the following vulnerability has been resolved: net: bridge: fix vlan tunnel dst null     pointer dereference This patch fixes a tunnel_dst null pointer dereference due to lockless access in the     tunnel egress path. When deleting a vlan tunnel the tunnel_dst pointer is set to NULL without waiting a     grace period (i.e. while it's still usable) and packets egressing are dereferencing it without checking.
    Use READ/WRITE_ONCE to annotate the lockless use of tunnel_id, use RCU for accessing tunnel_dst and make     sure it is read only once and checked in the egress path. The dst is already properly RCU protected so we     don't need to do anything fancy than to make sure tunnel_id and tunnel_dst are read only once and checked     in the egress path. (CVE-2021-47223)

  - In the Linux kernel, the following vulnerability has been resolved: bpf: Guard stack limits against 32bit     overflow This patch promotes the arithmetic around checking stack bounds to be done in the 64-bit domain,     instead of the current 32bit. The arithmetic implies adding together a 64-bit register with a int offset.
    The register was checked to be below 1<<29 when it was variable, but not when it was fixed. The offset     either comes from an instruction (in which case it is 16 bit), from another register (in which case the     caller checked it to be below 1<<29 [1]), or from the size of an argument to a kfunc (in which case it can     be a u32 [2]). Between the register being inconsistently checked to be below 1<<29, and the offset being     up to an u32, it appears that we were open to overflowing the `int`s which were currently used for     arithmetic.

When skb is cloned into skb2 and     passed to icmp6_send(), it uses IP6CB(skb2). IP6CB interprets the IPv4 inet_skb_parm as an inet6_skb_parm.
    The cipso offset in inet_skb_parm.opt directly overlaps with dsthao in inet6_skb_parm at offset 18. If an     attacker sends a forged ICMPv4 error with a CIPSO IP option, dsthao would be a non-zero offset. Inside     icmp6_send(), mip6_addr_swap() is called and uses ipv6_find_tlv(skb, opt->dsthao, IPV6_TLV_HAO). This     would scan the inner, attacker-controlled IPv6 packet starting at that offset, potentially returning a     fake TLV without checking if the remaining packet length can hold the full 18-byte struct     ipv6_destopt_hao. Could mip6_addr_swap() then perform a 16-byte swap that extends past the end of the     packet data into skb_shared_info? Should the cb array also be cleared in ip6_err_gen_icmpv6_unreach() and     ip6ip6_err() to prevent this? This patch implements the first suggestion. I am not sure if ip6ip6_err()     needs to be changed. A separate patch would be better anyway. (CVE-2026-43038)

The caller of rxe_srq_from_init()     (rxe_create_srq) eventually calls rxe_srq_cleanup() upon receiving the error, which triggers a second     rxe_queue_cleanup() on the same memory, leading to a double free.

  - In the Linux kernel, the following vulnerability has been resolved: RDMA/uverbs: Validate wqe_size before     using it in ib_uverbs_post_send ib_uverbs_post_send() uses cmd.wqe_size from userspace without any     validation before passing it to kmalloc() and using the allocated buffer as struct ib_uverbs_send_wr. If a     user provides a small wqe_size value (e.g., 1), kmalloc() will succeed, but subsequent accesses to     user_wr->opcode, user_wr->num_sge, and other fields will read beyond the allocated buffer, resulting in an     out-of-bounds read from kernel heap memory. This could potentially leak sensitive kernel information to     userspace. Additionally, providing an excessively large wqe_size can trigger a WARNING in the memory     allocation path, as reported by syzkaller. This is inconsistent with ib_uverbs_unmarshall_recv() which     properly validates that wqe_size >= sizeof(struct ib_uverbs_recv_wr) before proceeding. Add the same     validation for ib_uverbs_post_send() to ensure wqe_size is at least sizeof(struct ib_uverbs_send_wr).

  - In the Linux kernel, the following vulnerability has been resolved: gfs2: Fix slab-use-after-free in     qd_put Commit a475c5dd16e5 (gfs2: Free quota data objects synchronously) started freeing quota data     objects during filesystem shutdown instead of putting them back onto the LRU list, but it failed to remove     these objects from the LRU list, causing LRU list corruption. This caused use-after-free when the shrinker     (gfs2_qd_shrink_scan) tried to access already-freed objects on the LRU list. Fix this by removing qd     objects from the LRU list before freeing them in qd_put(). Initial fix from Deepanshu Kartikey     <kartikey406@gmail.com>. (CVE-2026-45861)

  - In the Linux kernel, the following vulnerability has been resolved: gfs2: Fix use-after-free in iomap     inline data write path The inline data buffer head (dibh) is being released prematurely in     gfs2_iomap_begin() via release_metapath() while iomap->inline_data still points to dibh->b_data. This     causes a use-after-free when iomap_write_end_inline() later attempts to write to the inline data area. The     bug sequence: 1. gfs2_iomap_begin() calls gfs2_meta_inode_buffer() to read inode metadata into dibh 2.
    Sets iomap->inline_data = dibh->b_data + sizeof(struct gfs2_dinode) 3. Calls release_metapath() which     calls brelse(dibh), dropping refcount to 0 4. kswapd reclaims the page (~39ms later in the syzbot report)     5. iomap_write_end_inline() tries to memcpy() to iomap->inline_data 6. KASAN detects use-after-free write     to freed memory Fix by storing dibh in iomap->private and incrementing its refcount with get_bh() in     gfs2_iomap_begin(). The buffer is then properly released in gfs2_iomap_end() after the inline write     completes, ensuring the page stays alive for the entire iomap operation. Note: A C reproducer is not     available for this issue. The fix is based on analysis of the KASAN report and code review showing the     buffer head is freed before use. [agruenba: Take buffer head reference in gfs2_iomap_begin() to avoid     leaks in gfs2_iomap_get() and gfs2_iomap_alloc().] (CVE-2026-45984)
