CVE-2026-64358

A flaw was found in the Linux kernel's media component, specifically within the mtk-jpeg driver. An internal function attempts to cancel a background task even when that task is not active on certain system configurations. This can lead to the system logging warning messages, potentially causing...

CVE-2026-64391

A flaw was found in ksmbd, the in-kernel Server Message Block SMB daemon. This vulnerability allows a remote attacker to bypass security restrictions by incorrectly handling credentials for Alternate Data Streams ADS input/output I/O operations. Instead of using the credentials established when t...

CVE-2026-64374

A flaw was found in the Linux kernel's real-time RT scheduler. In non-real-time configurations, the RTPUSHIPI mechanism, designed to improve task migration, can lead to a live lock. This occurs when a CPU handling heavy network traffic is repeatedly interrupted by other CPUs attempting to schedul...

UBUNTU-CVE-2026-64556

In the Linux kernel, the following vulnerability has been resolved: perf/core: Detach event groups during removeonexec perfeventremoveonexec removes events by calling perfeventexitevent. For top-level events, this removes the event from the context with DETACHEXIT only. This can leave inconsisten...

kernel: blk-mq: pop cached request if it is usable

A flaw was found in the Linux kernel's blk-mq component. This use-after-free vulnerability occurs when a task attempts to submit a bio a data structure for I/O operations to blk-mq. If the task is interrupted and sleeps after checking for a cached request but before using it, the cached request c...

CVE-2026-64485

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA compress module. The sndcomprtasknew function, responsible for creating driver tasks, does not properly handle errors during the validation of Direct Memory Access DMA buffers or file descriptor reservation. This...

CVE-2026-64226

In the Linux kernel, the following vulnerability has been resolved: schedext: Avoid UAF in scxrootenableworkfn init failure path In scxrootenableworkfn, puttaskstructp is called before scxerror dereferences p-comm and p-pid. If the iterator's reference is the last drop, the task is freed...

SUSE CVE-2026-64359

In the Linux kernel, the following vulnerability has been resolved: nilfs2: reject CLEANSEGMENTS ioctl with out-of-range segment numbers Syzbot reported a hung task in nilfstransactionbegin where multiple tasks performing chmod on a nilfs2 mount blocked for over 143 seconds waiting to acquire...

SUSE CVE-2026-64374

In the Linux kernel, the following vulnerability has been resolved: sched/rt: Have RTPUSHIPI be default off for non PREEMPTRT RT migration is done aggressively. When a CPU schedules out a high priority RT task for a lower priority task, it will look to see if there's any RT tasks that are waiting...

In the Linux kernel, the following vulnerability has been resolved: proc: protect ptracemayaccess with execupdatelock FD links procpidgetlink and procpidreadlink currently look up the task from the pid once, then do the ptrace access check on that task, then look up the task from the pid a second...

CVE-2026-64513

CVE-2026-64513 affects the Linux kernel KVM x86 path, where CR8 intercept is recomputed on PPR update. Root cause: after a patch to speed up TPR below-threshold vmexits, apic_update_ppr() can omit a deliverable interrupt, causing kvm_lapic_update_cr8_intercept() and vmx_update_cr8_intercept() to ...

CVE-2026-64485

The CVE-2026-64485 issue concerns the Linux kernel ALSA compress module. In snd_compr_task_new(), the driver task is allocated before validating DMA buffers and reserving file descriptors. If validation or FD reservation fails, the core frees wrappers and DMA references without invoking the drive...
