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 5.15

A flaw in memory writing within the Linux kernel’s UDF file system functionality was discovered. This flaw allows a user to trigger certain file operations, which in turn triggers udfwritefi. A local user could exploit this flaw to crash the system or potentially cause other malicious actions...

Astra Linux – Vulnerability in Linux 5.10

A NULL pointer dereference flaw was discovered in the Linux kernel’s Amateur Radio AX.25 protocol functionality, regarding the way a user connects to the protocol. This flaw allows a local user to crash the system...

Astra Linux – Vulnerability in Linux 5.15

A flaw was discovered in the unrestricted use of the BPFBTFLOAD function, which could lead to an out-of-bounds memory write in the Linux kernel’s BPF subsystem due to the way a user loads BTFs. This flaw allows a local user to crash the system or escalate their privileges...

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 found in Linux 5.10, Linux 5.15

A stack overflow flaw was discovered in the Linux kernel’s SYSCTL subsystem regarding how a user modifies certain kernel parameters and variables. This flaw allows a local user to crash the system or potentially escalate their privileges on the system...

Astra Linux – Vulnerability in Linux 5.10

A NULL pointer dereference flaw was discovered in the Linux kernel’s X.25 set of standardized network protocol functions. This flaw allows a local user to crash the system by terminating their session using a simulated Ethernet card while continuing to use that connection...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

A flaw was discovered in the Linux Kernel’s RDS Reliable Datagram Sockets protocol. The rdsrmzerocopycallback function uses listentry on the head of a list, resulting in a type confusion. A local user can trigger this with the rdsmessageput function. This type confusion causes the struct...

Astra Linux – Vulnerability in Linux 5.10

An integer overflow flaw was discovered in the Linux kernel’s virtio device driver code, where a user triggers the vhostvdpaconfigvalidate function. This flaw allows a local user to crash the system or potentially escalate their privileges on the system...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

A use-after-free flaw was discovered in vcsread in drivers/tty/vt/vc-screen.c within vc-screen in the Linux Kernel. This issue may allow an attacker with local user access to cause a system crash or leak internal kernel information...

Astra Linux – Vulnerability in Linux, Linux 5.10

A race condition accessing file objects in the Linux kernel OverlayFS subsystem was identified. This occurs when users renames files using OverlayFS in a specific manner. A local user could exploit this flaw to cause the system to crash...

Astra Linux – Vulnerability in Linux 5.10

A vulnerability was discovered in the Linux kernel’s blockinvalidatepage function in the fs/buffer.c file of the filesystem. A missing sanity check may allow a local attacker with user privileges to cause a denial of service DOS issue...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

A memory write vulnerability that is outside the bounds of the system’s protection was discovered in the Linux kernel’s Kid-friendly Wired Controller driver. This vulnerability allows a local user to crash the system or potentially escalate their privileges. The issue lies in the bigbenprobe...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15
