Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: schedext: Fixed unsafe locking in the scxdumpstate function. For kernels built with CONFIGPREEMPTRT=y, the dumplock will be converted to a sleepable spinlock instead of a disable-irq one. This can lead to the following scenarios:...

CVE-2026-31647

CVE-2026-31647 concerns the Linux kernel idpf driver. The vulnerability stems from improper nesting of PREEMPT_RT raw/BH spinlocks during asynchronous VC handling, which could yield an invalid wait context. A fix switches from the completion’s raw spinlock to a local lock in the idpf_vc_xn struct...

CVE-2026-23134

In the Linux kernel, the following vulnerability has been resolved: slab: fix kmallocnolock context check for PREEMPTRT On PREEMPTRT kernels, locallock becomes a sleeping lock. The current check in kmallocnolock only verifies we're not in NMI or hard IRQ context, but misses the case where...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the kmallocnolock function not properly checking the context within the PREEMPTRT kernel. This ma...
