CVE-2026-50264 [HIGH] CWE-787 CVE-2026-50264: An out-of-bounds write flaw was found in the X.Org X server and Xwayland in DRIGetBuffers/DRIGetBuff An out-of-bounds write flaw was found in the X.Org X server and Xwayland in DRIGetBuffers/DRIGetBuffersWithFormat. A client that requests multiple DRI2BufferBackLeft attachments and one DRI2BufferFrontLeft can trigger an out-of-bounds heap write. This may be used to crash the server, or for privilege escalation if the X server runs as root.

CVE-2022-1587 [CRITICAL] CWE-125 CVE-2022-1587: An out-of-bounds read vulnerability was discovered in the PCRE2 library in the get_recurse_data_leng An out-of-bounds read vulnerability was discovered in the PCRE2 library in the get_recurse_data_length() function of the pcre2_jit_compile.c file. This issue affects recursions in JIT-compiled regular expressions caused by duplicate data transfers.

CVE-2026-3833 [HIGH] CWE-178 CVE-2026-3833: A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive compari A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of `nameConstraints` labels, specifically for `dNSName` (DNS) or `rfc822Name` (email) constraints within `excludedSubtrees` or `permittedSubtrees`. A remote attacker can exploit this by crafting a leaf certificate with casing differences in the Subje

CVE-2023-2156 [HIGH] CWE-617 CVE-2023-2156: A flaw was found in the networking subsystem of the Linux kernel within the handling of the RPL prot A flaw was found in the networking subsystem of the Linux kernel within the handling of the RPL protocol. This issue results from the lack of proper handling of user-supplied data, which can lead to an assertion failure. This may allow an unauthenticated remote attacker to create a denial of service condition on the system.

CVE-2019-17631 [CRITICAL] CWE-285 CVE-2019-17631: From Eclipse OpenJ9 0.15 to 0.16, access to diagnostic operations such as causing a GC or creating a From Eclipse OpenJ9 0.15 to 0.16, access to diagnostic operations such as causing a GC or creating a diagnostic file are permitted without any privilege checks.

CVE-2011-3631 [HIGH] CWE-190 CVE-2011-3631: Hardlink before 0.1.2 has multiple integer overflows leading to heap-based buffer overflows because Hardlink before 0.1.2 has multiple integer overflows leading to heap-based buffer overflows because of the way string lengths concatenation is done in the calculation of the required memory space to be used. A remote attacker could provide a specially-crafted directory tree and trick the local user into consolidating it, leading to hardlink executable cr

CVE-2004-1235 [MEDIUM] CVE-2004-1235: Race condition in the (1) load_elf_library and (2) binfmt_aout function calls for uselib in Linux ke Race condition in the (1) load_elf_library and (2) binfmt_aout function calls for uselib in Linux kernel 2.4 through 2.429-rc2 and 2.6 through 2.6.10 allows local users to execute arbitrary code by manipulating the VMA descriptor.
