MediumCVSS 5.5 EPSS 0.13%
A flaw was found in sssd. A local user can cause a Denial of Service (DoS) by exhausting the responder service's available file descriptors (system handles used for open connections). By opening and maintaining many concurrent connections to a responder socket while continuing to...
-
MediumCVSS 5.5 EPSS 0.13%
A flaw was found in SSSD. A local user can cause a denial of service (DoS) by disrupting system authentication services. When handling Generic Security Services Application Programming Interface (GSSAPI) authentication in the Pluggable Authentication Module (PAM) responder, cache...
-
MediumCVSS 5.5 EPSS 0.10%
A flaw was found in SSSD. An unprivileged local user can repeatedly request master automount map updates through the autofs responder due to missing authorization checks. This triggers global cache invalidation and forces repeated lookups to backend directory providers, leading t...
-
MediumCVSS 5.5 EPSS 0.10%
A flaw was found in SSSD. In configurations where the autofs responder service is enabled, memory allocated during successful request processing is not released until the client connection terminates. A local attacker can exploit this vulnerability by maintaining an open connecti...
-
MediumCVSS 5.5 EPSS 0.13%
A flaw was found in SSSD. A local attacker can exploit this vulnerability by sending a specially crafted request to the autofs responder UNIX socket. Due to improper buffer offset calculation during request parsing, the service performs an out-of-bounds memory read. This flaw can...
-
CVE-2026-104030 Sssd: sssd: denial of service via out-of-bounds read during passkey parsing
PublishedMediumCVSS 5.5 EPSS 0.12%A flaw was found in sssd. This vulnerability allows a local user to cause a Denial of Service (DoS) by submitting a specially crafted passkey authentication token that lacks null terminators. The authentication service reads past the end of the provided memory buffer, causing the...
-
CVE-2026-90462 Sssd: sssd: fail-open in ldap ppolicy access check allows continued authorization
PublishedMediumCVSS 5.4 EPSS 0.18%A flaw was found in SSSD. When configured with the LDAP access provider and ldap_access_order including ppolicy or lockout, a fail-open condition in the LDAP ppolicy access check can occur if a user lookup returns zero results. This can incorrectly return success and cache an all...

CVE-2026-90996 Sssd: sssd: denial of service in nss responder via crafted zero-length requests
PublishedMediumCVSS 5.5 EPSS 0.13%A flaw was found in sssd. A local unprivileged user could send a specially crafted request with a zero-length body to the Network Security Services (NSS) responder. This could lead to a denial-of-service condition, causing the NSS responder to become unstable or terminate. This v...

CVE-2026-90995 Sssd: sssd: local denial of service due to null pointer dereference in pam responder
PublishedMediumCVSS 5.5 EPSS 0.14%A flaw was found in SSSD (System Security Services Daemon). A local attacker with privileges to connect to the PAM (Pluggable Authentication Modules) responder socket can send a specially crafted protocol request. If the pam_app_services configuration is enabled and the service i...

HighCVSS 8.4 EPSS 0.17%
A heap out-of-bounds write exists in the Photo CD (PCD) decoder of GraphicsMagick. In DecodeImage() (coders/pcd.c), the Huffman delta loop advances its output pointer with q++ after every decoded delta and never checks it against the end of the heap-allocated luma/chroma plane bu...
-
HighCVSS 7.1 EPSS 0.13%
A flaw was found in SSSD. The extract_authtok_v1() function in the PAM responder does not validate the auth_token_length field against the remaining buffer size before processing. A local attacker can exploit this via a crafted protocol v1 request to the PAM responder socket, cau...
-
CVE-2026-68744 Sssd: sssd: nss responder uninitialized heap disclosure in initgroups reply
PublishedLowCVSS 3.3 EPSS 0.13%A flaw was found in SSSD. The sss_nss_protocol_fill_initgr() 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 ca...

CVE-2026-68742 Sssd: sssd: nss responder out-of-bounds read via unchecked addrlen in gethostbyaddr
PublishedMediumCVSS 5.5 EPSS 0.13%A flaw was found in SSSD. The sss_nss_protocol_parse_addr() function in the NSS responder does not validate the addrlen field against the remaining packet body size. A local attacker can exploit this via a crafted GETHOSTBYADDR request to the NSS responder socket, causing an out-...
-
MediumCVSS 6.4 EPSS 0.12%
A flaw was found in sssd. When authenticating with a YubiKey, the SSSD PAM responder can crash due to a use-after-free vulnerability, where a memory pointer is incorrectly handled. A local attacker could exploit this flaw by manipulating smartcard or YubiKey contents, leading to...
-
MediumCVSS 5.5 EPSS 0.19%
A content injection vulnerability was found in the ABRT post-create event handler scripts in libreport. The event script queries the systemd journal for log entries matching the crashed process and writes the results to files in the dump directory without sanitizing embedded cont...
-
HighCVSS 7.8 EPSS 0.23%
A symlink following vulnerability was found in the ABRT post-create event handler scripts in libreport. Event scripts write output files using shell redirections without the O_NOFOLLOW flag. If the target file is replaced with a symlink, the shell process running as root follows...
-
MediumCVSS 5.5 EPSS 0.16%
A flaw was found in the System Security Services Daemon (SSSD). The pam_passkey_child_read_data() function within the PAM passkey responder fails to properly handle raw bytes received from a pipe. Because the data is treated as a NUL-terminated C string without explicit terminati...
-
HighCVSS 8.8 EPSS 0.18%
A flaw was found in libinput. A local attacker who can place a specially crafted Lua bytecode file in certain system or user configuration directories can bypass security restrictions. This allows the attacker to run unauthorized code with the same permissions as the program usin...
-
MediumCVSS 5.5 EPSS 0.15%
A flaw was found in libinput. An attacker capable of deploying a Lua plugin file in specific system directories can exploit a dangling pointer vulnerability. This occurs when a garbage collection cleanup function is called, leaving a pointer that can then be printed to system log...
