Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerabilities have been resolved: Wifi: mac80211: Fixed an underflow in staticbranchdec for aqldisable. syzbot reported an underflow in staticbranchdec in aqlenablewrite. 0 The issue arises because aqlenablewrite does not serialize concurrent write operations ...
SUSE CVE-2026-72154
In the Linux kernel, the following vulnerability has been resolved: openrisc: Fix jumplabel smp syncing The original commit 8c30b0018f9d "openrisc: Add jump label support" copies from arm64 and does not properly consider how icache invalidation on remote cores works in OpenRISC. On OpenRISC remot...

CVE-2026-31551
The CVE-2026-31551 entry relates to the Linux kernel mac80211 wifi subsystem. A race in aql_enable_write() during concurrent debugfs writes can cause a static_branch_dec() underflow because the code checks static_key_false(&aql_disable.key) and then later increments/decrements the static branch, ...
