…_rcu() jira VULN-54021 cve-pre CVE-2025-21764 commit-author Jiri Pirko <jiri@nvidia.com> commit 2034d90 Make the net pointer stored in possible_net_t structure annotated as an RCU pointer. Change the access helpers to treat it as such. Introduce read_pnet_rcu() helper to allow caller to dereference the net pointer under RCU read lock.

jira VULN-54021 cve-pre CVE-2025-21764 commit-author Eric Dumazet <edumazet@google.com> commit 482ad2a dev->nd_net can change, readers should either use rcu_read_lock() or RTNL. We currently use a generic helper, dev_net() with no debugging support. We probably have many hidden bugs. Add dev_net_rcu() helper for callers using rcu_read_lock() protection.

jira VULN-171982 cve CVE-2025-68724 commit-author Thorsten Blum <thorsten.blum@linux.dev> commit df0845c Use check_add_overflow() to guard against potential integer overflows when adding the binary blob lengths and the size of an asymmetric_key_id structure and return ERR_PTR(-EOVERFLOW) accordingly. This prevents a possible buffer overflow when copying data from potentially malicious X.509 certificate fields that can be arbitrarily large, such as ASN.1 INTEGER serial numbers, issuer names, etc. Fixes: 7901c1a ("KEYS: Implement binary asymmetric key ID handling") Signed-off-by: Thorsten Blum <thorsten.blum@linux.dev> Reviewed-by: Lukas Wunner <lukas@wunner.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> (cherry picked from commit df0845c) Signed-off-by: CIQ Kernel Automation <ciq_kernel_automation@ciq.com>

jira VULN-176434 cve CVE-2026-23216 commit-author Maurizio Lombardi <mlombard@redhat.com> commit 9411a89 In iscsit_dec_conn_usage_count(), the function calls complete() while holding the conn->conn_usage_lock. As soon as complete() is invoked, the waiter (such as iscsit_close_connection()) may wake up and proceed to free the iscsit_conn structure. If the waiter frees the memory before the current thread reaches spin_unlock_bh(), it results in a KASAN slab-use-after-free as the function attempts to release a lock within the already-freed connection structure. Fix this by releasing the spinlock before calling complete().

jira VULN-184555 cve CVE-2026-43190 commit-author Florian Westphal <fw@strlen.de> commit 735ee85 Quoting reporter: In net/netfilter/xt_tcpmss.c (lines 53-68), the TCP option parser reads op[i+1] directly without validating the remaining option length. If the last byte of the option field is not EOL/NOP (0/1), the code attempts to index op[i+1]. In the case where i + 1 == optlen, this causes an out-of-bounds read, accessing memory past the optlen boundary (either reading beyond the stack buffer _opt or the following payload).

jira VULN-183034 cve CVE-2026-31685 commit-author Zhengchuan Liang <zcliangcn@gmail.com> commit fdce0b3 `eui64_mt6()` derives a modified EUI-64 from the Ethernet source address and compares it with the low 64 bits of the IPv6 source address. The existing guard only rejects an invalid MAC header when `par->fragoff != 0`. For packets with `par->fragoff == 0`, `eui64_mt6()` can still reach `eth_hdr(skb)` even when the MAC header is not valid. Fix this by removing the `par->fragoff != 0` condition so that packets with an invalid MAC header are rejected before accessing `eth_hdr(skb)`.
