CVE-2026-46037 ipv4: icmp: validate reply type before using icmp_pointers

In the Linux kernel, the following vulnerability has been resolved: ipv4: icmp: validate reply type before using icmppointers Extended echo replies use ICMPEXTECHOREPLY as the outbound reply type. That value is outside the range covered by icmppointers, which only describes the traditional ICMP...

CVE-2026-46037

The CVE-2026-46037 issue affects the Linux kernel IPv4 ICMP component. Extended echo replies could use ICMP_EXT_ECHOREPLY outside the icmp_pointers[] range; the fix avoids icmp_pointers[] lookups for out-of-range types and uses array_index_nospec() for in-range lookups. Multiple OS feeds report p...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified openSUSE Tumbleweed versions prior to kernel-devel-7.0.11-1.1 Description A flaw exists in the IPv4 ICMP implementation where the system fails to validate the reply type before accessing the icmp...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Added a bounds check on patindex to prevent out-of-bounds kernel reads in madvise. When a user provides a bogus patindex value through the madvise IOCTL, the xepatindexgetcohmode function performs an array access without...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: dma-buf: heaps: Fixed potential Spectre v1 gadget It appears that nr could be a Spectre v1 gadget, as it is provided by a user and used as an array index. This issue prevents the contents of kernel memory from being leaked to use...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: netlink: prevents potential Spectre v1 exploits Most netlink attributes are parsed and validated via nlavalidateparse or validatenla. c u16 type = nlatypenla; if type == 0 || type maxtype / Error or continue / The @type value is...

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

In 64-bit versions of the Linux kernel, Copyfromuser does not implement uaccessbeginnospec, which allows a user to bypass the “accessok” check and pass a kernel pointer to copyfromuser. This would enable an attacker to leak sensitive information. We recommend upgrading beyond commit...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: gpio: Prevent potential speculation leaks in gpiodevicegetdesc The userspace may trigger a speculative read of an address outside the gpio descriptor array. Users can do this by calling gpioioctl with an offset that is out of...

SUSE CVE-2026-43280

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Add bounds check on patindex to prevent OOB kernel read in madvise When user provides a bogus patindex value through the madvise IOCTL, the xepatindexgetcohmode function performs an array access without validating bounds...

CVE-2026-31781

In the Linux kernel, the following vulnerability has been resolved: drm/ioc32: stop speculation on the drmcompatioctl path The drm compat ioctl path takes a user controlled pointer, and then dereferences it into a table of function pointers, the signature method of spectre problems. Fix this up b...

CVE-2026-31781

CVE-2026-31781 concerns the Linux kernel drm/ioc32 compat ioctl path, where a user-controlled pointer was used to index a table of function pointers (spectre-like pattern). The issue is mitigated by applying array_index_nospec on the index to the function-pointer list, as described in the fix. Co...

EUVD-2026-24846

In the Linux kernel, the following vulnerability has been resolved: s390/syscalls: Add spectre boundary for syscall dispatch table The s390 syscall number is directly controlled by userspace, but does not have an arrayindexnospec boundary to prevent access past the syscall function pointer tables...

CVE-2026-31483

In the Linux kernel, the following vulnerability has been resolved: s390/syscalls: Add spectre boundary for syscall dispatch table The s390 syscall number is directly controlled by userspace, but does not have an arrayindexnospec boundary to prevent access past the syscall function pointer tables...

CVE-2026-31483

CVE-2026-31483 affects the s390 architecture in the Linux kernel. The root cause is a missing array_index_nospec() boundary in the syscall dispatch table, allowing a user-controlled syscall number to exceed the function pointer table and potentially read kernel memory via speculative execution (S...
