CVE-2025-39964 crypto: af_alg - Disallow concurrent writes in af_alg_sendmsg

In the Linux kernel, the following vulnerability has been resolved: crypto: afalg - Disallow concurrent writes in afalgsendmsg Issuing two writes to the same afalg socket is bogus as the data will be interleaved in an unpredictable fashion. Furthermore, concurrent writes may create inconsistencie...

SUSE CVE-2023-53599

In the Linux kernel, the following vulnerability has been resolved: crypto: afalg - Fix missing initialisation affecting gcm-aes-s390 Fix afalgallocareq to initialise areq-firstrsgl.sgl.sgt.sgl to point to the scatterlist array in areq-firstrsgl.sgl.sgl.

SUSE CVE-2025-39931

In the Linux kernel, the following vulnerability has been resolved: crypto: afalg - Set merge to zero early in afalgsendmsg If an error causes afalgsendmsg to abort, ctx-merge may contain a garbage value from the previous loop. This may then trigger a crash on the next entry into afalgsendmsg whe...

CVE-2023-53599

CVE-2023-53599: In the Linux kernel, the af_alg crypto path for gcm-aes-s390 had a missing initialisation in af_alg_alloc_areq. The bug could cause an oops when gcm_walk_start() runs on req->dst because req->dst was incorrectly set from areq->first_rsgl.sgl.sgl by _aead_recvmsg() calling...

PT-2025-40762

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The Linux kernel contains a flaw within the crypto/af alg subsystem, specifically impacting the gcm-aes-s390 driver. A missing initialization in af alg alloc areq can lead to an issue...

PT-2025-41786

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The Linux kernel contains an issue in the crypto/af alg module where concurrent writes to the same af alg socket can lead to data interleaving and inconsistencies in the internal socket...

kernel: crypto: algif_hash - fix double free in hash_accept

In the Linux kernel, the following vulnerability has been resolved: crypto: algifhash - fix double free in hashaccept If accept2 is called on socket type algifhash with MSGMORE flag set and cryptoahashimport fails, sk2 is freed. However, it is also freed in afalgrelease, leading to...

SUSE CVE-2025-37808

In the Linux kernel, the following vulnerability has been resolved: crypto: null - Use spin lock instead of mutex As the null algorithm may be freed in softirq context through afalg, use spin locks instead of mutexes to protect the default null algorithm...

PT-2026-2874

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The Linux kernel's crypto subsystem contains an issue where memory allocated via sock kmalloc was not zero-initialized. This affected several crypto user API contexts and requests, relyi...

SUSE CVE-2018-14619

A flaw was found in the crypto subsystem of the Linux kernel before version kernel-4.15-rc4. The "null skcipher" was being dropped when each afalgctx was freed instead of when the aeadtfm was freed. This can cause the null skcipher to be freed while it is still in use leading to a local user bein...

kernel: af_alg_release() in crypto/af_alg.c neglects to set a NULL value for a certain structure member, which leads to a use-after-free in sockfs_setattr

In the Linux kernel afalgrelease in crypto/afalg.c neglects to set a NULL value for a certain structure member, which leads to a use-after-free UAF in sockfssetattr. A local attacker can use this flaw to escalate privileges and take control of the system...
