gnutls: gnutls: Information disclosure via heap overread in RSA key exchange

A flaw was found in libgnutls. A remote attacker, by sending an extremely short premaster secret during an RSA key exchange to a server using an RSA key backed by a PKCS11 token, could trigger a short heap overread. This memory corruption vulnerability could lead to information disclosure...

CVE-2026-58058 Nmap - Integer Underflow in IPv6 Extension Header Parsing

Nmap through 7.99 does not keep the IPv6 extension-header walk within the captured packet in ipv6getdataprimitive libnetutil/netutil.cc, so the pointer advances past the buffer and the remaining-length computation underflows to a large value. A scanned target or on-path attacker returning a craft...

SUSE CVE-2026-57451

Vim is an open source, command line text editor. Prior to 9.2.0670, gettextprops in src/textprop.c reads a uint16 property count stored inline after a line's text and returns it as the number of 32-byte textpropT entries that follow. The only check is a floor that guarantees room for a single...

DEBIAN-CVE-2026-53309

In the Linux kernel, the following vulnerability has been resolved: ocfs2/dlm: fix off-by-one in dlmmatchregions region comparison The local-vs-remote region comparison loop uses '=' instead of '', causing it to read one entry past the valid range of qrregions. The other loops in the same functio...

CVE-2026-53023

A flaw was found in the Linux kernel's NTFS3 file system driver. The ntfsfillsuper function, responsible for loading the volume label, did not properly null-terminate the converted UTF-8 label. This oversight could allow the ntfs3labelshow function to read beyond the allocated buffer when...

CVE-2026-53149

A flaw was found in the Linux kernel's Thunderbolt driver. The tbpropertyparsedir function, responsible for parsing root directory content, does not properly validate the size of the content against the allocated block size. This oversight allows the system to read beyond the intended memory...

CVE-2026-53241

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA sequencer dummy port. This vulnerability arises from a stack overread when processing Universal MIDI Packet UMP events, where the system attempts to copy a UMP-sized packet into a smaller, legacy-sized stack storage. Th...
