In the Linux kernel, the following vulnerability has been resolved: net/atm: fix slab-out-of-bounds read in vccsetsockopt vccsetsockopt contained an ineffective optlen check: if SOLEVELMATCHoptname, level && optlen != SOSIZEoptname return -EINVAL; If SOLEVELMATCHoptname, level evaluated to false...

CVE-2026-74689

CVE-2026-74689 is a slab-out-of-bounds read in the Linux kernel's net/atm subsystem, specifically in vcc_setsockopt(). The root cause is an ineffective optlen validation: when __SO_LEVEL_MATCH(optname, level) evaluates to false, the length check is short-circuited and bypassed, allowing copy_from...

CVE-2026-74594

This Linux kernel vulnerability is a use-after-free in the Pressure Stall Information (PSI) subsystem. A race between psi_schedule_rtpoll_work() (called locklessly from the scheduler hotpath) and psi_trigger_destroy() allows the rtpoll_timer to be re-armed after the cgroup is freed, causing poll_...

In the Linux kernel, the following vulnerability has been resolved: sched ext: Take cgroup lock first in scx cgroup lock scx cgroup lock write-locks scx cgroup ops rwsem and then takes cgroup lock, which can deadlock through kernfs: scx enable/disable cgroup rmdir cpu.weight write...

CVE-2026-74483

A flaw was found in the binfmtmisc component of the Linux kernel. An unprivileged local attacker, operating under specific memory constraints a tight memory cgroup, could repeatedly trigger a failure in the bmfillsuper function during a mount operation. This failure prevents the proper release of...

kernel: sched/psi: fix race between file release and pressure write

A flaw was found in the Linux kernel's Pressure Stall Information PSI subsystem. A race condition exists between the file release and pressure write operations, specifically concerning the priv member of struct kernfsopenfile. This can lead to a use-after-free vulnerability or a NULL dereference,...

CVE-2026-74305

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. This vulnerability allows a program without cgroup storage to bypass compatibility checks when bridging tail call chains. This could enable unintended interactions between programs with and without cgroup storage,...

CVE-2026-72010

A flaw was found in the Linux kernel's cgroup/cpuset component. A local user can exploit this by configuring a child cpuset without explicitly setting its memory nodes. When a CPU hotplug event occurs, a division-by-zero error is triggered during memory policy rebind, leading to a system crash...

CVE-2026-72213

A flaw was found in the Linux kernel's huge page memory management hugetlb. A mismatch in how reserved and non-reserved huge page control group cgroup charges are handled during memory allocation and deallocation can lead to an incorrect cgroup being uncharged. This issue results in a page counte...

CVE-2026-72427

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter cgroup program handling. Incorrect indexing in the replaceeffectiveprog and purgeeffectiveprogs functions, particularly when BPFFPREORDER programs are active, can lead to memory corruption. This issue can result in overwriting...
