Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: LoongArch: KVM: Check the validity of “numcpu” from user space. The maximum supported CPU number is EIOINTCROUTEMAXVCPUS. For the irchip EIOINTC, validation of the CPU number is added to prevent array pointer overflow...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: tee: added a overflow check in registershmhelper When special lengths are provided by the user space, registershmhelper may cause an integer overflow when calculating the number of pages covered by a given user space memory regio...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: posix-timers: A potential memory leak was identified in dotimercreate. When creating a posix timer with allocation of a specific timer ID, if there are issues with accessing the value in the user space, the function terminates...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: BPF: Fixed potential improper dereferencing of pointers in bpfsysbpf. The bpfsysbpf helper function allows an eBPF program to load another eBPF program from within the kernel. In this case, the argument union bpfattr pointer...

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

In the Linux kernel, the following vulnerability has been resolved: rcv: process: Fix kernel gp leakage childregs represents the registers that are active for the new thread in the user context. For a kernel thread, childregs-gp is never used, as the kernel’s gp value is not touched by the switch...

Astra Linux – Vulnerability in Linux, Linux 5.10

A flaw was discovered in the Linux kernel. This flaw allows an attacker to crash the Linux kernel by simulating amateur radio from the user space, resulting in a null-ptr-deref vulnerability and a use-after-free vulnerability...

SUSE CVE-2025-40048

In the Linux kernel, the following vulnerability has been resolved: uiohvgeneric: Let userspace take care of interrupt mask Remove the logic to set interrupt mask by default in uiohvgeneric driver as the interrupt mask value is supposed to be controlled completely by the user space. If the mask b...

CVE-2026-43332

In the Linux kernel, the following vulnerability has been resolved: thermal: core: Fix thermal zone device registration error path If thermalzonedeviceregisterwithtrips fails after registering a thermal zone device, it needs to wait for the tz-removal completion like thermalzonedeviceunregister, ...

Linux Distros Unpatched Vulnerability : CVE-2026-43315

"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - KVM: nSVM: Remove a user-triggerable WARN on nestedsvmloadcr3 succeeding Drop the WARN in svmsetnestedstate on nestedsvmloadcr3 failing as it is trivially easy...

AZL-85863 CVE-2026-43258 affecting package kernel 6.6.150.1-1

In the Linux kernel, the following vulnerability has been resolved: alpha: fix user-space corruption during memory compaction Alpha systems can suffer sporadic user-space crashes and heap corruption when memory compaction is enabled. Symptoms include SIGSEGV, glibc allocator failures e.g...

CVE-2026-43258

CVE-2026-43258 concerns the Linux kernel: on Alpha systems, memory compaction can trigger user-space crashes and heap corruption due to insufficient TLB shootdown during page migration. Root cause involves ASN rollover and stale instruction translations surviving migration. The fix introduces a m...
