CVE-2026-90050

CVE-2026-90050 affects the Linux kernel 's fq qdisc (Fair Queue) in net/sched. The root cause is that the fq change path accepts TCA_FQ_QUANTUM in [1, INT_MAX] and TCA_FQ_INITIAL_QUANTUM up to INT_MAX, while fq_init() already clamps to [1, 1<<20]. A user with CAP_NET_ADMIN can override the ...

A user can override the init clamp v...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: Wifi: For the cfg80211 driver, the value of NL80211ATTRTXQQUANTUM was restricted. syzbot is capable of triggering soft lockups by setting NL80211ATTRTXQQUANTUM to 2^31. We had a similar issue in the schfq driver, which was fix...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net/sched: schfq: Fix for integer overflow of “credit”. If schfq is configured with “initial quantum” values greater than INTMAX, the first assignment of “credit” will cause signed integer overflow, resulting in a very negative...

Astra Linux – Vulnerability in imagemagick

A flaw was discovered in ImageMagick within MagickCore/quantum.h. An attacker who submits a crafted file processed by ImageMagick could induce undefined behavior, resulting in values that are outside the range of type unsigned char. This likely leads to a disruption in the application’s...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: sched: schcake: bounds checks were added to the host bulk flow fairness counts. Although we fixed a logic error in the commit cited below, the syzbot still managed to cause an underflow in the per-host bulk flow counters, resulti...
