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...

CVE-2026-9084

MISP’s OIDC authentication plugin allowed automatic linking of an OIDC identity to an existing local user account based on the email claim when the local account had no stored sub value. Under insecure or untrusted IdP configurations where email ownership is not enforced, an attacker with a valid...

CVE-2026-9087 Keycloak: cross-session email verification proof not bound to upstream identity in first-broker-login

A flaw was found in Keycloak. The cross-session verification proof is keyed only by local userId, idpAlias and is not bound to the upstream identity that was actually verified, so a second upstream account on the same IdP can consume it and get linked to the victim's local account...

CVE-2026-9084 MISP OIDC authentication bypass via automatic email-based account linking under insecure IdP configurations

MISP’s OIDC authentication plugin allowed automatic linking of an OIDC identity to an existing local user account based on the email claim when the local account had no stored sub value. Under insecure or untrusted IdP configurations where email ownership is not enforced, an attacker with a valid...

CVE-2026-9084

MISP OIDC authentication plugin is affected. The issue allows automatic linking of an OIDC identity to an existing local user account based on the email claim when the local account has no stored sub value. Under insecure/untrusted IdP configurations where email ownership isn’t enforced, an attac...

CVE-2026-41054

In src/havegecmd.c, the sockethandler function performs a credential check on the abstract UNIX socket \0/sys/entropy/haveged. However, while it detects if the connecting user is not root cred.uid != 0 and prepares a negative acknowledgement ASCIINAK, it fails to stop execution. The code proceeds...

Astra Linux – Vulnerability in Linux 5.10

A use-after-free flaw was discovered in the Linux kernel’s Memory Management subsystem, where a user can win two races simultaneously due to a failure in the masprevSlot function. This issue could allow a local user to crash the system...

Astra Linux – Vulnerability in Linux 5.10

An information leak flaw was discovered due to uninitialized memory in the Linux kernel’s TIPC protocol subsystem, during the process of a user sending a TIPC datagram to one or more destinations. This flaw allows a local user to read certain parts of the kernel’s memory. The affected data is no...

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...

cpython: CPython: Logging Bypass in Legacy .pyc File Handling

A flaw was found in CPython. This vulnerability allows a local user with low privileges to bypass security auditing mechanisms. The issue occurs because the SourcelessFileLoader component, responsible for handling older Python compiled files .pyc, does not properly trigger system audit events. Th...

crun: crun: Privilege escalation due to incorrect parsing of the `--user` option

A flaw was found in crun, an open-source OCI Container Runtime. A local user can exploit this vulnerability due to incorrect parsing of the --user option when using crun exec. The value 1 is misinterpreted as root privileges User ID 0 and Group ID 0 instead of the intended User ID 1 and Group ID ...
