Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: media: coda: Added a check for codairamalloc. Since codairamalloc may return a NULL pointer, it is better to check the return value to avoid dereferencing a NULL pointer, just like with the other cases...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: “phy: qcom-qmp-combo: fix NULL-deref on runtime resume” The commit with ID fc64623637da “phy: qcom-qmp-combo,usb: add support for separate PCSUSB region” began treating the PCSUSB registers as potentially separate from the PCS...

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: media: platform: mtk-mdp3: Added a missing check and a call to free for idaalloc. Added a check on the return value of idaalloc to avoid NULL pointer dereferencing. Additionally, freed the allocated ctx-id if mdpm2mopen fails...

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...

In the Linux kernel, the following vulnerability has been resolved: Net: Ethernet: stmmac: fixed the altrtsepcs function when using a fixed-link. When using a fixed-link, the altrtsepcs driver crashes due to a null-pointer dereference, as no phydevice is provided to the tsepcsfixmacspeed function...

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 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.
