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 in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Staging: rtl8723bs: osdep: Avoid NULL pointer dereferencing in rtwcbufalloc. The return value of kzallocflex is used without ensuring that the allocation succeeds, and the pointer is dereferenced unconditionally. Protect access t...

Astra Linux – Vulnerability in Linux 5.15

A NULL pointer dereference flaw was discovered in the Linux kernel’s AMD Sensor Fusion Hub driver. This flaw 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: media: rockchip: rkcif: Added the “MUSTCONNECT” flag to the pads. The pads failed to check for connected devices, which may lead to a null dereference when the stream is enabled. It is impossible to handle a NULL pointer...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: drm/xe/hdcp: Added a NULL check for mediagt in intelhdcpgsccheckstatus. When media GT is disabled via configfs, there is no allocation for mediagt, which is set to NULL. In such scenarios, intelhdcpgsccheckstatus results in a...

In the Linux kernel, the following vulnerability has been resolved: platform/chrome: crosectypec: Init mutex in Thunderbolt registration The function crostypecregisterthunderbolt failed to initialize the adata-lock mutex. This results in a NULL dereference when the mutex is acquired later e.g., i...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: Prevent NULL derefrence when RX memory is exhausted The CPU receives frames from the MAC through conventional DMA: the CPU allocates buffers for the MAC, then the MAC fills those buffers and returns ownership to the...

Astra Linux – Vulnerability in Linux 5.15

A NULL pointer dereference flaw was discovered in the Linux kernel’s KVM module. This flaw can lead to a denial of service in the x86emulateinsn function in arch/x86/kvm/emulate.c. The flaw occurs when an illegal instruction is executed on the guest CPU of the Intel model...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: octeonep VF: Added NULL checks for napibuildskb. The napibuildskb function can return NULL when allocation fails. In octep VFoqprocessrx, the result is used directly without a NULL check in both the single-buffer and...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: erofs: Fixed an issue where inline data reading failed for ztailpacking pclusters. Compressed folios for ztailpacking pclusters must be valid before adding these pclusters to I/O chains. Otherwise, zerofsdecompresspcluster may...

Astra Linux – Vulnerability in Linux 5.15

A issue was discovered in the Linux kernel through version 5.16-rc6. The function rtwinitxmitpriv in drivers/staging/r8188eu/core/rtwxmit.c lacks a check on the return value of rtwallochwxmits, which can lead to a null pointer derefrence...

Astra Linux – Vulnerability in Linux 5.15

A flaw in the NULL Pointer Dereference mechanism within the Linux kernel’s NTFS3 driver function attrpunchhole was identified. A local user could exploit this flaw to crash the system...

Astra Linux – Vulnerability in Linux 5.15

A null pointer dereference issue was detected in the can protocol in the net/can/afcan.c file in Linux before Linux. The mlpriv variable may not be initialized in the receive path of CAN frames. A local user could exploit this flaw to crash the system or potentially cause a denial of service...

CVE-2026-55204

HAProxy through 3.4.0, fixed in commit 9a6d1fe, contains a null pointer dereference vulnerability in hpackdhtinsert within src/hpack-tbl.c that fails to validate the return value of hpackdhtdefrag when the memory pool is exhausted. An attacker can trigger HPACK dynamic table insertions under memo...

PT-2026-50890

Name of the Vulnerable Software and Affected Versions NI grpc-device versions prior to 2.17.0 Description A NULL pointer dereference occurs in the data moniker service of NI grpc-device. A NULL pointer dereference is a condition where a program attempts to read or write to a memory address that i...
