In the Linux kernel, the following vulnerability has been resolved: arm64: asm-bug: Add .align 2 to the end of BUGENTRY. When CONFIGDEBUGBUGVERBOSE=n, we fail to add the necessary padding bytes to the bugtable entries. As a result, the last entry in a bug table will be ignored, potentially leadin...

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

In the Linux kernel, the following vulnerabilities have been resolved: s390/dasd: fixed an issue where error recovery led to data corruption on ESE devices. Extent Space Efficient ESE or thin-provisioned volumes need to be formatted on demand during normal IO processing. The dasdeseneedsformat...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Destroying vGIC structures during failed vCPU creation If the function kvmarchvcpucreate fails to share the vCPU page with the hypervisor, we propagate the error back to the ioctl, but leave the vGIC vCPU structures...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: s390/sclp: Fixed the check for NULL values in the SCCB field. The tracing code called by the SCLP interrupt handler contains early exits if the SCCB address associated with an interrupt is NULL. This check is performed after the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: In the net subsystem, for the dsa module, the microchip function has been updated to include a condition for scheduling the kszmibreadwork function. When the ksz module is installed or removed using the rmmod command, the kernel...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: iommu/arm-smmu-v3: checking the return value after calling platformgetresource. This will cause a null-ptr-deref if platformgetresource returns NULL; therefore, we need to check the return value...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: x86/kexec: fixed the memory leak in the elf header buffer. This issue was reported by the kmemleak detector: Unreferenced object 0xffffc900002a9000 size 4096: comm “kexec”, pid 14950, jiffies 4295110793 age 373.951s Hex dump firs...

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

In the Linux kernel, the following vulnerability has been resolved: s390/ptrace: The handling of setting the fpc register was corrected. If the value of the floating-point control fpc register of a traced process is modified using the ptrace interface, the new value is tested for validity by...

In the Linux kernel, the following vulnerabilities have been resolved: Tracing: Ensure visibility when inserting an element into tracingmap. Running the following two commands in parallel on a multi-processor AArch64 machine may occasionally generate an unexpected warning regarding duplicate...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: ARM: hisi: Add missing ofnodeput after offindcompatiblenode The offindcompatiblenode function will increment the refcount of the returned devicenode. Calling ofnodeput is necessary to avoid a refcount leak...

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: MIPS: Do not crash in stacktop for tasks without an ABI or vDSO Not all tasks have an ABI associated with them, or a vDSO mapped to them. For example, kthreads never have such an ABI. If such a task calls stacktop, it will...

Astra Linux – Vulnerability in Golang-1.19, Golang-1.23

Due to the use of a variable time instruction in the assembly implementation of an internal function, a small number of bits from secret scalars are leaked on the ppc64le architecture. Given the way this function is used, we believe that this leakage is not sufficient to allow recovery of the...
