Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: net/mlx5: The port select structure is cleared when attempting to create it. The port select structure is cleared in case of an error, so no stale values remain after the definers are destroyed. This is because the...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: usb: typec: ucsi: displayport: Fixed the OOB altmode array index issue. The UCSI displayport driver indexes the port’s altmode array using the GETCURRENTCAM response. This indexing occurs after checking that the value of...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net/sched: taprio: avoid disabling offload when it was never enabled In a rather strange API design decision, qdisc-destroy is called even if qdisc-init never succeeded. This isn’t exclusive to the commit 87b60cfacf9f “netsched:...

kernel: gfs2: Fix unlikely race in gdlm_put_lock

A flaw was found in the Linux kernel’s Global File System 2 implementation affecting distributed lock manager DLM handling in the gdlmputlock function. During an unmount operation, if the DFLUNMOUNT flag is set but the lockspace has not yet been fully released, remote callbacks gdlmast or gdlmbas...

CVE-2026-100073

A flaw was found in the Linux kernel's ext4 file system. When saving modified memory pages back to storage, the system underestimates the journal transaction space required to split and update file block mappings. A local user could exploit this flaw by performing specific write operations,...

CVE-2026-100075

A flaw was found in the Linux kernel's SCSI Remote Direct Memory Access Protocol SRP target driver. When memory allocation fails while processing multi-buffer descriptors, the error-handling routine fails to reset internal tracking counters and leaves an invalid memory pointer. A remote client...

kernel: net: ipv6: use-after-free in fib6_rule_suppress due to stale res->rt6 pointer

A use-after-free vulnerability was found in the Linux kernel's IPv6 FIB rule lookup path. In fib6rulesuppress, when a route is suppressed and released via ip6rtputflags, the res-rt6 pointer is not cleared. If no later rule supplies a replacement route, fib6rulelookup returns the stale freed rt6in...

CVE-2026-97986

A flaw was found in the Linux kernel's virtioinput driver. A race condition during device removal can lead to a Denial of Service DoS via a kernel crash. Because the driver unregisters the input device before resetting the underlying virtual device, in-flight event callbacks may access freed devi...

CVE-2026-97978

A flaw was found in the Linux kernel's Intel Ethernet driver ice. Event tracing routines dereferenced internal data pointers when formatting log messages instead of capturing the necessary values when the event was recorded. A local user with administrative access or tracing privileges could...

CVE-2026-97942

A flaw was found in the Linux kernel's x86 instruction patching subsystem. A race condition between runtime instruction modification text poking and page attribute updates can cause virtual memory lookup failures in shared executable memory. A local user can trigger this issue during kernel modul...

CVE-2026-97489

A flaw was found in the Linux kernel's BFS Boot File System implementation. The kernel fails to properly verify the return value when setting the block size during a mount operation. A local user with permissions to mount file systems could exploit this issue by mounting an incompatible file syst...

CVE-2026-97927

A flaw was found in the Linux kernel's Unix File System UFS implementation. This vulnerability allows a local user to cause a Denial of Service DoS by mounting a specially crafted or corrupted file system image. During a failed mount operation, an improper cleanup sequence leads to a null pointer...

CVE-2026-97925

A flaw was found in the Linux kernel's timer tick broadcast subsystem. A race condition occurs when installing a replacement clock event device concurrently with ongoing tick broadcast operations, causing the system to attempt to arm a detached timer device. If the central processing unit CPU...

CVE-2026-97916

A flaw was found in the Linux kernel's Intel VPU ivpu driver. A compromised device firmware can cause a Denial of Service DoS by modifying log buffer metadata in shared memory. Because the host driver re-reads buffer size fields from shared memory after validating them, the firmware can alter the...

CVE-2026-97601

A flaw was found in the Linux kernel's 6LoWPAN IPv6 over Low-Power Wireless Personal Area Networks networking subsystem, which can lead to a Denial of Service DoS. When a network device changes its link type without properly initializing internal data pointers, the kernel fails to validate the...
