However, it is also freed in af_alg_release, leading to slab-use-after-free error. CVE-2025-38079 SUSE Linux Micro 6.0:kernel-livepatch-6_4_0-25-default-6-1.2 important To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2025/suse-su-202520641-1/ https://www.suse.com/security/cve/CVE-2025-38079.html CVE-2025-38079 https://bugzilla.suse.com/1245217 SUSE Bug 1245217 https://bugzilla.suse.com/1245218 SUSE Bug 1245218 In the Linux kernel, the following vulnerability has been resolved: net_sched: prio: fix a race in prio_tune() Gerrard Tai reported a race condition in PRIO, whenever SFQ perturb timer fires at the wrong time. The race is as follows: CPU 0 CPU 1 [1]: lock root [2]: qdisc_tree_flush_backlog() [3]: unlock root | | [5]: lock root | [6]: rehash | [7]: qdisc_tree_reduce_backlog() | [4]: qdisc_put() This can be abused to underflow a parent's qlen. Calling qdisc_purge_queue() instead of qdisc_tree_flush_backlog() should fix the race, because all packets will be purged from the qdisc before releasing the lock. CVE-2025-38083 SUSE Linux Micro 6.0:kernel-livepatch-6_4_0-25-default-6-1.2 important To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2025/suse-su-202520641-1/ https://www.suse.com/security/cve/CVE-2025-38083.html CVE-2025-38083 https://bugzilla.suse.com/1245183 SUSE Bug 1245183 https://bugzilla.suse.com/1245350 SUSE Bug 1245350 In the Linux kernel, the following vulnerability has been resolved: HID: core: do not bypass hid_hw_raw_request hid_hw_raw_request() is actually useful to ensure the provided buffer and length are valid. Directly calling in the low level transport driver function bypassed those checks and allowed invalid paramto be used. CVE-2025-38494 SUSE Linux Micro 6.0:kernel-livepatch-6_4_0-25-default-6-1.2 important To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2025/suse-su-202520641-1/ https://www.suse.com/security/cve/CVE-2025-38494.html CVE-2025-38494 https://bugzilla.suse.com/1247349 SUSE Bug 1247349 https://bugzilla.suse.com/1247350 SUSE Bug 1247350 In the Linux kernel, the following vulnerability has been resolved: HID: core: ensure the allocated report buffer can contain the reserved report ID When the report ID is not used, the low level transport drivers expect the first byte to be 0. However, currently the allocated buffer not account for that extra byte, meaning that instead of having 8 guaranteed bytes for implement to be working, we only have 7. CVE-2025-38495 SUSE Linux Micro 6.0:kernel-livepatch-6_4_0-25-default-6-1.2 important To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2025/suse-su-202520641-1/ https://www.suse.com/security/cve/CVE-2025-38495.html CVE-2025-38495 https://bugzilla.suse.com/1247348 SUSE Bug 1247348 https://bugzilla.suse.com/1247351 SUSE Bug 1247351
