Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: drm/xe: The numsyncs parameter has been limited to prevent excessively large allocations. The exec and vmbind ioctls allow userspace to specify an arbitrary numsyncs value. Without proper bounds checking, a very large numsyncs...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: nvmet-tcp: bounds checks were added in nvmettcpbuildpduiovec. The nvmettcpbuildpduiovec function could exceed the range of cmd-req.sg when the PDU length or offset exceeds sgcnt, and then use bogus values for sg-length/offset...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: scsi: target: iscsi: Fixed a use-after-free in iscsitdecsessionusagecount. In iscsitdecsessionusagecount, the function calls complete while holding the sess-sessionusagelock. Similar to the connection usage counting logic, the...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, the progressivedecompresstileupgrade function detected mismatches using progressiverfxquantcmpequal, but only emitted a WLogWARN message; execution continued. The wrapped value 247 was used as a shift...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-mixer: us16x08: validate meter packet indices The getmeterlevelsfromurb function parses the 64-byte meter packets sent by the device and fills the per-channel arrays meterlevel, complevel, and masterlevel in the struct...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: Timers: Fixed a NULL function pointer race condition in timershutdownsync. There is a race condition between timershutdownsync and timerexpiration, which can lead to a WARNON being triggered in expiretimers. The issue occurs...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. The ainputsendinputevent function caches the channelcallback in a local variable and then uses it without synchronization. A concurrent closure of a channel can free or reinitialize the callback, resulting in an use-after-free...

Astra Linux – Vulnerability in libcap2

A flaw was discovered in libcap. A local unprivileged user can exploit a Time-of-check-to-time-of-use TOCTOU race condition in the capsetfile function. This allows an attacker with write access to a parent directory to redirect file capability updates to a file controlled by the attacker. By doin...

Astra Linux – Vulnerability in expat

In libexpat before version 2.7.4, the doContent function does not properly determine the buffer size bufSize, as there is no check for integer overflow during the reallocation of the tag buffer...

Astra Linux – Vulnerability in libssh

A flaw was discovered in libssh. The API function sshgethexa is vulnerable to a denial-of-service attack when processing zero-length inputs. This vulnerability can be exploited remotely by an attacker during GSSAPI Generic Security Service Application Program Interface authentication, if the...

Astra Linux – Vulnerability in GraphicsMagick

GraphicsMagick before 8e56520 has a heap-based buffer over-read issue in the ReadJXLImage function, located in coders/jxl.c, related to a call to ImportViewPixelArea...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: can: mcbausb: mcbausbreadbulkcallback: fixed a URB memory leak. The memory leak was fixed in a similar manner to the issue in commit 7352e1d5932a “can: gsusb: gsusbreceivebulkcallback: fixed a URB memory leak”. In mcbausbprobe -...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: tls: Fixed a race condition in tlsswcancelworktx This issue was discovered during a code audit. After the tlsskprotoclose function is called, canceldelayedworksync can still be used from functions like Delayed ACK handler or...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: scsi: core: There is a race condition where the error handler is only awakened when the last running command completes or times out. This race condition can cause the SCSI layer to fail to awaken the error handler, resulting i...

Astra Linux – Vulnerability in libsoup3

A flaw was discovered in libsoup’s SoupServer. A remote attacker could exploit a use-after-free vulnerability, where the soupserverdisconnect function releases connection objects prematurely, even if a TLS handshake is still pending. If the handshake completes after the connection object has been...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in QEMU. When reading input audio from the virtio-snd device’s input callback, the virtiosndpcmincb function did not check whether the iov could accommodate the data buffer, potentially leading to a heap out-of-bounds write. This issue persists due to an incomplete fix for...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: leds: led-class: Only add the LED to ledslist when it is fully ready. Before this change, the LED was added to ledslist before the ledinitcore function was called—that is, before ledclassdev.setbrightnesswork was initialized. Thi...
