Astra Linux – Vulnerability in Linux 5.10, Linux

A NULL pointer dereference flaw was discovered in the UNIX protocol, specifically in the file net/unix/diag.c, within unixdiaggetexact in the Linux kernel. The newly allocated skb does not have an sk, resulting in a NULL pointer. This flaw could allow a local user to crash the system or potential...

Astra Linux – Vulnerability in Linux 5.10, Linux

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 5.10

A flaw was discovered in the subsequent getuserpagesfast function within the Linux kernel’s interface for symmetric key cipher algorithms, specifically in the skcipherrecvmsg function of the crypto/algifskcipher.c file. This flaw allows a local user to crash the system...

Astra Linux – Vulnerability in Linux 5.10, Linux

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 – Vulnerability in Linux 5.10, Linux

A memory leak flaw was discovered in the Linux kernel’s Stream Control Transmission Protocol. This issue may occur when a user initiates a malicious networking service, and someone connects to this service. This could allow a local user to deplete resources, resulting in a denial of service...

A null pointer dereference flaw was discovered in the hugetlbfsfillsuper function within the Linux kernel’s hugetlbfs Huge TLB pages functionality. This issue may allow a local user to crash the system or potentially escalate their privileges on the system...

kernel: Linux kernel: Denial of service and memory corruption in RDMA umad

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA umad User Mode Access Device component. A local user can exploit this vulnerability by manipulating input, causing an integer underflow that leads to an out-of-bounds memory write. This memory corruption can result in a denia...

PT-2026-42199

Name of the Vulnerable Software and Affected Versions Keycloak affected versions not specified Description A flaw exists where the cross-session verification proof is keyed only by the userId and idpAlias and is not bound to the upstream identity that was actually verified. This allows a second...

sudo: Sudo: Privilege escalation due to failure in privilege drop calls

A flaw was found in Sudo. A local user could exploit a failure in the setuid, setgid, or setgroups calls, which are used to drop privileges before running the mailer. This oversight allows for privilege escalation, enabling the user to gain elevated access on the system...

OpenSSH: OpenSSH: Low integrity impact from unconfirmed proxy-mode multiplexing sessions

A flaw was found in OpenSSH. This vulnerability allows for a low integrity impact due to the omission of connection multiplexing confirmation for proxy-mode multiplexing sessions. A local user, under specific and complex conditions requiring user interaction, could potentially establish a...

CVE-2026-43492

A flaw was found in the Linux kernel. A local user could trigger an integer underflow in the mpireadrawfromsgl function within the lib/crypto: mpi component. This occurs when invoking a KEYCTLPKEYENCRYPT system call with a larger output length than input length and providing a zero-filled input...
