In the Linux kernel, the following vulnerability has been resolved: media: az6007: Fixed nullptrderef in az6007i2cxfer In az6007i2cxfer, msg is controlled by the user. When msgi.buf is null and msgi.len is zero, previous checks on msgi.buf will still be performed. Malicious data will eventually...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: hwmon: pmbuscore Fixed NULL pointer dereferencing. Pass i2cclient to pmbusisenabled to remove the assumption that a regulator device is passed in. This will fix the issue of NULL pointer dereferencing when called from pmbusgetfla...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Wifi: ath12k – Avoid NULL pointer access during management transmit cleanup. Currently, the ar reference is not added in skbcb. Although this reference is generally not used during transmit completion callbacks, during interface...

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 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: qede: ensure that the skb is allocated before use. qedebuildskb assumes that buildskb always works and proceeds directly to skbreserve. However, buildskb may fail under memory pressure. This results in a kernel panic because the...

Astra Linux – Vulnerability in Ceph

A flaw was discovered in Ceph, related to URL processing on RGW backends. An attacker can exploit this issue by providing a null URL, causing the RGW to crash and resulting in a denial of service...

Astra Linux – Vulnerability in libstb

stbimage is a single-file library licensed under MIT, used for processing images. If stbiloadgifmain in stbiloadgiffrommemory fails, it returns a null pointer and may leave the z variable uninitialized. If the caller also sets the vertical flipping flag, the process continues by calling...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/i915: Obtaining inteldisplay from the encoder to avoid potential issues. Obtain inteldisplay from “encoder” instead of “state” within the encoder hooks. This avoids the problematic behavior caused by intelsanitizeencoder, whi...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: intel: A possible null-ptr-deref issue in ebunandprobe has been fixed. This issue could lead to a null-ptr-deref when using ‘res’. If platformgetresource returns NULL, moving using ‘res’ after devmioremapresource wi...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: gpio: Restrict the use of GPIO chip IRQ members before initialization. The IRQ members of the GPIO chip are exposed before they can be fully initialized, which leads to race conditions. One such issue was observed with the...

In the Linux kernel, the following vulnerabilities have been resolved: hwmon: w83793 Fixed NULL pointer dereferencing by removing unnecessary structure fields. If the driver reads a temporary value that satisfies the following conditions: tmp & 0x08 && !tmp & 0x80 && tmp & 0x7 == tmp 4 & 0x7 from...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: tipc: Check for a null pointer after calling kmemdup kmemdup may return a null pointer, so it is necessary to check for this. Otherwise, the null pointer will be dereferenced later in tipccryptokeyxmit, as can be seen in the trac...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fixed a NULL dereference bug. The issue arises when this function is called from ntfsloadattrlist. The value of “size” is calculated as le32tocpuattr-res.datasize. On 64-bit systems, this does not cause an overflow, but...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: drm: Fixed a potential null-ptr-deref due to drmmmodeconfiginit. drmmmodeconfiginit will call drmmodecreatestandardproperties, and it does not check the return value. When drmmodecreatestandardproperties fails due to allocatio...
