Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: rcv: kexec: Avoid deadlock in the kexec crash path. If the kexec crash code is called in the interrupt context, the machinekexecmaskinterrupts function will trigger a deadlock while trying to acquire the irqdesc spinlock...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries: Fixed the crash caused by the scv instruction with kexec. Kexec on pseries disables AIL reloconexc, which is required for supporting scv instructions. This happens before other CPUs have been shut down. This mean...

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

In the Linux kernel, if the IMA appraisal method is used with the “imaappraiselog” boot parameter, lockdown can be circumvented using kexec on any machine when Secure Boot is disabled or unavailable. IMA prevents the “imaappraiselog” parameter from being set during boot, but this does not cover...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: x86/mm, kexec, ima: Use memblockfreelate instead of imafreekexecbuffer. The code that calls imafreekexecbuffer is executed long after the memblock allocator has already been removed. This could lead to a use-after-free in...
