kernel: Linux kernel: Denial of Service due to NULL function pointer race in timer shutdown

A flaw was found in the Linux kernel. A race condition exists in the timershutdownsync function, where a timer's function pointer can be set to NULL while the timer is still active on another processor. This can be exploited by a local attacker to trigger a kernel warning, potentially leading to...

CVE-2026-68744 Sssd: sssd: nss responder uninitialized heap disclosure in initgroups reply

A flaw was found in SSSD. The sssnssprotocolfillinitgr function in the NSS responder pre-allocates reply space for all group entries but does not shrink the packet when groups are skipped, causing uninitialized heap bytes to be transmitted to the client. A local attacker can exploit this to...

CVE-2026-40553

A flaw was found in gawk. A buffer overflow vulnerability exists in the ftype routine, located in the extension/readdir.c program file. This vulnerability could allow an attacker to crash the program, resulting in a denial of service. It may also potentially lead to arbitrary code execution, thou...

crypto/x509: crypto/tls: golang: Go: Denial of Service vulnerability in certificate chain building

A flaw was found in the Go standard library packages crypto/x509 and crypto/tls. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being...

crypto/x509: golang: Go crypto/x509: Denial of Service via inefficient certificate chain validation

A flaw was found in Go's crypto/x509 package. A remote attacker could exploit this by presenting a specially crafted certificate chain containing a large number of policy mappings. This inefficient validation process consumes excessive resources, which can lead to a denial of service DoS for...

sssd: sssd: sudo LDAP provider searches entire directory tree for sudoRole objects by default, enabling privilege escalation

A flaw was found in SSSD's LDAP sudo provider. When the ldapsudosearchbase option is not explicitly configured, SSSD searches the entire LDAP directory tree for sudoRole objects. An authenticated attacker with write access to any subtree can inject a sudoRole object granting root-level sudo...
