Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: PCI: ofproperty: Return error for intmap allocation failure The “-ENOMEM” return value occurs when kcalloc fails to prevent a NULL pointer dereferencing in this case. bhelgaas: commit log...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: PCI/AER: Avoid NULL pointer dereferencing in aerratelimit When platform firmware provides error information to the OS, for example, via the ACPI APEI GHES mechanism, it may identify a device that does not advertise an AER...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: sfc: Fixed the null pointer dereference in efxhardstartxmit. Trying to access the channel through the txqueue variable is incorrect because we can only be in this situation if txqueue is NULL. Therefore, we should not dereference...

In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Fixed null ndlp pointer dereferencing in an abnormal exit path for GFTID An error case resulting from exiting from lpfccmplctcmdgftid causes a call to lpfcnlpput, where a null pointer is used to reference the nodelist...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: serial: core: Clearing the circular buffer before NULLifying it The circular buffer is NULLified in the uartttyportshutdown function, under the spin lock. However, the PM or other timer-based callbacks may still trigger after thi...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: In the ofmodalias function, we can pass the str and len parameters. This could lead to a kernel oops in vsnprintf, as the function only allows passing a NULL pointer when the length is also 0. Additionally, we need to filter out...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: lltemac: The function platformgetresource was replaced with the function devmplatformioremapresourcebyname. This replacement occurs because the function platformgetresource is called using 0 as its name. This issue ultimatel...

Astra Linux – Vulnerability in Linux, Linux 5.10

A race condition flaw was discovered in the Linux kernel sound subsystem due to improper locking mechanisms. This could lead to a NULL pointer derefrence during the handling of the SNDCTLDSPSYNC ioctl command. A privileged local user such as root or a member of the audio group could exploit this...

Astra Linux – Vulnerability in Linux, Linux 5.10

A NULL pointer dereference flaw was discovered in the btrfsrmdevice function in fs/btrfs/volumes.c within the Linux Kernel. Triggering this bug requires ‘CAPSYSADMIN’. This flaw allows a local attacker to crash the system or leak internal kernel information. The greatest threat posed by this...

Astra Linux – Vulnerability in Linux 5.15

A NULL pointer dereference flaw was discovered in the Linux kernel’s drivers/gpu/drm/msm/msmgemsubmit.c code, specifically in the submitlookupcmds function. This flaw occurs because there is no check on the return value of kmalloc. This issue allows a local user to crash the system...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Added a NULL check for ‘replay’ in ‘edpsetreplayallowactive’. In the first if statement, we are checking whether ‘replay’ is NULL. However, in the second if statement, we do not check whether ‘replay’ is NULL aga...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: afs: Fixed dynamic root getattr The recent patch to modify afagetattr to consult the server did not take into account the pseudo-inodes used by the dynamic root-type afa superblock. As a result, there was an oops when such a...

Astra Linux – Vulnerability in Linux 5.15

A issue was discovered in the Linux kernel through version 5.16-rc6. The function imxregisteruartclocks in drivers/clk/imx/clk.c lacks a check on the return value of kcalloc, which can lead to a null pointer dereferencing...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: phy: ti: phy-omap-usb2: Fixed NULL pointer dereferencing for SRP. If the external PHY working together with phy-omap-usb2 does not implement sendsrp, we may still attempt to call it. This can occur on an idle Ethernet device that...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ext4: Update sjournalinum if it changes after journal replay. When mounting a crafted ext4 image, sjournalinum may change after journal replay. This is obviously unreasonable, because we have successfully loaded and replayed the...
