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 in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: perf: Improved missing SIGTRAP checks To detect missing SIGTRAP checks, we use a WARN in perfeventoverflow. This warning is triggered if pendingsigtrap was already set—meaning the process returns to user space without consuming...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: xfrm: Zero padding when dumping algorithms and encap templates. When copying data to user-space, we must ensure that only valid data is copied. Padding in structures may contain random potentially sensitive data and should never ...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: KVM: x86/pmu: Disabled support for adaptive PEBS. Support for virtualizing adaptive PEBS has been discontinued. This is because KVM’s implementation is architecturally broken without an obvious or easy way to address this issu...

"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...

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...

CVE-2026-43258

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...

SUSE CVE-2026-43073

In the Linux kernel, the following vulnerability has been resolved: x86-64: rename misleadingly named 'copyusernocache' function This function was a masterclass in bad naming, for various historical reasons. It claimed to be a non-cached user copy. It is literally neither of those things. It's a...
