CVE-2026-14454 Imager versions before 1.033 for Perl treat unsigned EXIF IFD entry counts as signed

Imager versions before 1.033 for Perl treat unsigned EXIF IFD entry counts as signed. Imager mishandled large EXIF IFD entry count values, treating them as negative numbers. This could lead to an attempt to allocate a block nearly the size of the address space, which fails and kills the process. ...

CVE-2026-43185

A flaw was found in ksmbd within the Linux kernel. A remote attacker can exploit a signedness bug in the smbdirectpreparenegotiation function by sending a specially crafted preferredsendsize value during SMB direct negotiation. This manipulation leads to an incorrect size calculation, allowing a...
