Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: ksmbd: fixed the bug in the trap in smb2lock. If the lock count is greater than 1, the flags might contain an old value. This issue should be checked using the flags of smb Lock, not those of flags. This could lead to a bug in...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ASoC: amd: Adjusted error handling in case of absence of a codec device. The acpigetfirstphysicalnode function may return NULL in several situations e.g., no such device exists, ACPI table error, reference count drops to 0, etc...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mm: Avoid leaving partial pfn mappings in error cases. As Jann points out, PFN mappings are special. Unlike normal memory mappings, there is no lifetime information associated with the mapping—it’s just a raw mapping of PFNs,...

Astra Linux – Vulnerability in Squid

Squid is a caching proxy for the Web. In Squid versions prior to 7.2, a failure to redact HTTP authentication credentials during error handling allowed information disclosure. This vulnerability allowed scripts to bypass browser security protections and obtain the credentials used by trusted...

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 6.1

In the Linux kernel, the following vulnerability has been resolved: misc: microchip: pci1xxxx: A double-free operation occurred during error handling of gpauxbusprobe. When auxiliarydeviceadd returns an error, it then calls auxiliarialdeviceuninit. The callback function gpauxiliarydevicerelease...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: net/tls: Fixed the reversed sign in calls to tlserrabort. sk-skerr seems to expect a positive value, a convention that ktls doesn’t always follow, leading to memory corruption in other code. For example: c kworker...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: btrfs: The BUG function call has been removed after failing to insert a delayed directory index entry. Instead of calling BUG when we fail to insert a delayed directory index entry into the delayed node’s tree, we can simply...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: Net layer: dsa: fixed a crash if -getssetcount fails. If ds-ops-getssetcount fails, then the “count” value is a negative error code, such as -EOPNOTSUPP. Since “i” is a unsigned int, the negative error code is type-promoted to a...
