An out-of-bounds memory access flaw was discovered in the x25bind function in the net/x25/afx25.c file within the Linux kernel version v5.12-rc5. A failure in the bounds check allows a local attacker with a user account on the system to access out-of-bounds memory, resulting in a system crash or...

A flaw was discovered in the Linux kernel in versions prior to 5.4.92 regarding the BPF protocol. This flaw allows an attacker with a local account to disclose information about kernel internal addresses. The greatest threat posed by this vulnerability relates to confidentiality...

Astra Linux – Vulnerability in Linux

In the file drivers/pci/hotplug/rpadlpar/sysfs.c within the Linux kernel up to version 5.11.8, the RPA PCI Hotplug driver suffers a user-tolerable buffer overflow when writing a new device name to the driver from user space. This allows user space to write data directly to the kernel stack frame...

Astra Linux – Vulnerability in Linux

JIT compilers in the Linux kernel from version 5.11.12 have incorrect calculations of branch displacements, allowing them to execute arbitrary code within the kernel context. This issue affects the files arch/x86/net/bpfjitcomp.c and arch/x86/net/bpfjitcomp32.c...

Astra Linux – Vulnerability in Linux

In the Linux kernel before version 5.11.14, there is a use-after-free issue in the cipsov4genopt module, located in net/ipv4/cipsoipv4.c. This issue arises due to improper handling of the CIPSO and CALIPSO reference counts related to DOI definitions. As a result, an arbitrary value is written to...

In the Linux kernel, from drivers/block/nbd.c up to version 5.10.12, there is a use-after-free in the nbdaddsocket function. This issue could be triggered by local attackers who have access to the nbd device. The attack occurs during I/O requests at a certain point in device setup, specifically...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: net: caif: fixed a memory leak in caifdevicenotify In the event of a failure in caifenrolldev, the allocated linksupport will not be assigned to the corresponding structure. Therefore, simply free the allocated pointer in case of...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: can: j1939: fixed Use-after-Free, failed to increment the ref count of the skb while it was in use. This patch addresses a Use-after-Free issue identified by the syzbot. The problem arises when a skb is taken from the per-session...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: NFC: st21nfca – A memory leak was fixed in the device probe, and the phy-pendingskb variable was properly freed after allocation. However, it was forgotten to be freed during the error handling and removal processes, resulting in...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: cfg80211: Calling cfg80211stopap when switching from P2PGO type If the user-space tools switch from NL80211IFTYPEP2PGO to NL80211IFTYPEADHOC via sendmsgNL80211CMDSETINTERFACE, it does not call the cleanup function cfg80211stopap...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net/sched: actskbmod: Skip non-Ethernet packets Currently, tcfskbmodact assumes that packets use Ethernet as their L2 protocol, which is not always the case. For example, for CAN devices: bash $ ip link add dev vcan0 type vcan $ ...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ALSA: usx2y – Do not call freepagesexact with a NULL address. Unlike some other functions, we cannot pass a NULL pointer to freepagesexact. Add a proper NULL check to avoid potential errors...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: drm/nouveau/debugfs: fixed the memory leak when releasing files. When using singleopen to open a file, singlerelease should be called. Otherwise, the memory allocated with singleopen may be leaked...
