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

A vulnerability was discovered in the Linux kernel, specifically in the spkttyioreceivebuf2 function. This function dereferences the spkttyiosynth variable without checking whether it is NULL or not. This could lead to a NULL-ptr deref crash...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

With shadow paging enabled, the INVPCID instruction results in a call to kvmmmuinvpcidgva. If INVPCID is executed with CR0.PG=0, the invlpg callback is not set, and the result is a NULL pointer dereference...

In the Linux kernel, the following vulnerability has been resolved: drm/radeon: fixed a possible null pointer dereferencing issue. In radeonfpnativemode, the return value of drmmodeduplicate is assigned to mode, which could lead to a NULL pointer dereferencing issue upon failure of...

Astra Linux – Vulnerability in Linux

A vulnerability was discovered in the Linux kernel, where the function sunkbdreinit was executed after sunkbdinterrupt had been called, even before sunkbd was freed. Although the dangling pointer is set to NULL in sunkbddisconnect, there is still an alias in sunkbdreinit that leads to a...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: scsi: ibmvfc: The BUGON flag has been removed when the event pool is empty. In practice, the driver should never send more commands than are allocated to the event pool. If this happens, the code will assert the BUGON flag. In th...

Astra Linux – Vulnerability in Linux

A NULL pointer dereference flaw was discovered in the Linux kernel’s IEEE 802.15.4 wireless networking subsystem, regarding the way the user terminates the LR-WPAN connection. This flaw allows a local user to crash the system. The greatest threat posed by this vulnerability is to system...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

A null pointer dereference issue was discovered in the SCTP network protocol within the net/sctp/streamsched.c file in the Linux kernel. If the streamin allocation fails, the streamout resource is freed, allowing further access to it. A local user could exploit this vulnerability to crash the...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/i915/gt: Check setdefaultsubmission before dereferencing When the i915 driver firmware binaries are not present, the setdefaultsubmission pointer is not set. This pointer is still dereferenced during suspension anyway. A chec...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ext4: Publish jinode after initialization The ext4inodeattachjinode function publishes ei-jinode to concurrent users. It used to set ei-jinode before jbd2journalinitjbd inode, allowing a reader to observe a non-NULL jinode with...

Astra Linux – Vulnerability in protobuf

Dereferencing a null pointer when a null char is present in a prototype symbol. The symbol is parsed incorrectly, resulting in an unchecked call into the name of the prototype file during the generation of the resulting error message. Since the symbol is incorrectly parsed, the file value is...

Astra Linux – Vulnerability in glibc

nscd: Null pointer crash after a “notfound” response If the Name Service Cache Daemon’s nscd cache fails to add a “notfound” netgroup response to its cache, the client request may lead to a null pointer dereferencing. This flaw was introduced in glibc 2.15 when the cache was moved to nscd. This...
