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

The Linux kernel before version 6.2.9 has a race condition, which can lead to a use-after-free issue in the drivers/net/ethernet/qualcomm/emac/emac.c file. This issue occurs when a physically nearby attacker disconnects an EMAC-based device...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

A race condition was detected in the Linux kernel’s watch queue due to a missing lock in the piperesizering function. The specific flaw lies in the handling of pipe buffers. The problem arises from the lack of proper locking when performing operations on an object. This flaw allows a local user t...

A out-of-bounds memory access flaw was discovered in the Linux kernel, specifically in the relayfilereadstartpos function within kernel/relay.c in relayfs. This flaw could allow a local attacker to crash the system or leak internal kernel information...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ipack: ipoctal: fix module reference leak A reference to the carrier module was taken every time it was used, but it was only released once, when the final reference to the tty struct was removed. This issue was fixed by taking t...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: s390/syscalls: Added a spectre boundary for the syscall dispatch table. The s390 syscall number is directly controlled by the user space, but there is no arrayindexnospec boundary to prevent access beyond the syscall function...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: x86/kexec: Fixed the double-free of the elf header buffer. After the patch provided by b3e34a47f989 “x86/kexec: fix memory leak of elf header buffer”, the use of image-elfheaders in the error path of crashloadsegments is no longe...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: BPF: Rejected direct access to nullable PTRTOBUF pointers The checkmemaccess function matches PTRTOBUF via basetype, which removes the PTRMAYBENULL flag, allowing direct dereferencing without a null check. The map iterator ctx-ke...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: ipa: Hash tables are only reset when supported. Last year, the code that manages GSI channel transactions switched from using spinlock-protected linked lists to using indexes in the ring buffer used for a channel. Recently,...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ksmbd: Do not expire a session when a binding attempt fails. When a multichannel session binding request fails e.g., due to an incorrect password, the error path unconditionally sets sess-state to SMB2SESSIONEXPIRED. However,...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: In tcpconnrequest, do not call reqskfastopenremove. The syzbot reported the following issue in tcpconnrequest: 0 If a listener is closed while a TFO socket is being processed in tcpconnrequest, inetcskreqskqueueadd does not set...

In the Linux kernel, the following vulnerability has been resolved: Wifi: iwlwifi: dvm – Fixed a issue where memcpy was used for writing data that spanned multiple fields. The received TKIP key may be up to 32 bytes, as it may also contain MIC rx/tx keys. These keys are not used by iwlwifi, and...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: Media: MediTech; vcodec: Fix resource leaks in vdecmsgqueueinit. If any error occurs in vdecmsgqueueinit, we need to set “msgqueue-wdmaaddr.size = 0;”. Normally, this is done within the vdecmsgqueuedeinit function. However, if...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: vdpasim: A possible memory leak was fixed in vdpasimnetinit and vdpasimblkinit. When a fault is injected while probing a module, if deviceregister fails in vdpasimnetinit or vdpasimblkinit, and the refcount of kobject is not...
