CVE-2026-43452 netfilter: x_tables: guard option walkers against 1-byte tail reads

In the Linux kernel, the following vulnerability has been resolved: netfilter: xtables: guard option walkers against 1-byte tail reads When the last byte of options is a non-single-byte option kind, walkers that advance with i += opi + 1 ? : 1 can read opi + 1 past the end of the option area. Add...

CVE-2026-43452

CVE-2026-43452 affects the Linux kernel netfilter x_tables option walkers (xt_tcpudp and xt_dccp). The vulnerability arises when processing packet options: walkers that increment with i += op[i + 1] ? : 1 can read op[i + 1] past the end of the option area, enabling an out-of-bounds read. Multiple...

GHSA-P8XM-42R7-89XG wasmtime has a panic when allocating a table exceeding the size of the host's address space

Impact Wasmtime's allocation logic for a WebAssembly table contained checked arithmetic which panicked on overflow. This overflow is possible to trigger, and thus panic, when a table with an extremely large size is allocated. This is possible with the WebAssembly memory64 proposal where tables ca...

CVE-2026-43241

A flaw was found in the Linux kernel component ntbhwswitchtec.
