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 6.1

In the Linux kernel, the following vulnerability has been resolved: cpufreq: CPPC: Fixed a possible nullptrderef issue in cppcgetcpucost. cpufreqcpugetraw may return NULL if the CPU is not included in policy-cpus cpu mask, which could lead to a null pointer dereference. Therefore, check for NULL ...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Reject SEV-ES intra-host migration if vCPU creation is in progress Migrations of SEV-ES state are rejected if either the source or destination VM is actively creating a vCPU. This occurs when the kvmvmioctlcreatevcpu...

In the Linux kernel, the following vulnerabilities have been resolved: Firmware: armsdei: Fixed a bug where sleep operations occurred from an invalid context. Running a preempt-rt v6.2-rc3-rt1 based kernel on an Ampere Altra Triggers: - Bug: Sleeping function called from an invalid context at...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Netfilter: Use getrandomu32 instead of prandom. This issue may occur during the update of per-cpu rndstate from the user context, i.e., at the localout path. BUG: Using smpprocessorid in preemptible 00000000 code: nginx/2725...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: scsi: qla2xxx: Fixed a crash that occurred when I/O abort times out. During CPU hotplug, a crash was observed with the following stack: Call Trace: qla24xxprocessresponsequeue+0x42a/0x970 qla2xxx qla2x00startnvmemq+0x3a2/0x4b0...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: net: openvswitch: Fixed a race condition related to port output. Assume the following setup on a single machine: 1. An openvswitch instance with one bridge and default flows. 2. Two network namespaces: “server” and “client”. 3...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: spi: Fixed a use-after-free issue during controller registration failures. Be sure to also deregister from the driver core in case the per-cpu statistics allocation fails during controller registration, in order to avoid...

Astra Linux – Vulnerabilities in Linux-6.1, Linux-5.15, Linux-5.10

In the Linux kernel, the following vulnerability has been resolved: cpufreq: scmi: Fixed a nullptrderef in scmicpufreqgetrate. The cpufreqcpugetraw function may return NULL when the target CPU is not present in the policy-cpus mask. The scmicpufreqgetrate function does not check for this case,...

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

In the Linux kernel, the following vulnerabilities have been resolved: net/iucv: Fixed the size of interrupt data iucvirqdata needs to be 4 bytes larger. These bytes are not used by the iucv module, but are written by the z/VM hypervisor in case a CPU is deconfigured. Reported as: BUG...
