The vulnerability of the win_close() function in the Vim text editor allows a attacker to compromise the confidentiality, integrity, and accessibility of data.

The vulnerability of the winclose function in the Vim text editor relates to Vim’s attempt to access a window structure that has already been freed. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility of data...

cups: use-after-free in cupsdAcceptClient() in scheduler/client.c

A vulnerability was found in CUPS. This issue occurs due to logging data of free memory to the logging service AFTER the connection has been closed, when it should have logged the data immediately before the connection closed, resulting in a use-after-free in cupsdAcceptClient in scheduler/client...

Vulnerability of microprogramming software for Intel, AMD, ARM, and IBM processors: This vulnerability arises due to the creation of racing states in a speculative mode, which can lead to access to already freed memory areas. If the processor mispredicts the branching in the code, it allows a hacker to gain access to protected memory.

The vulnerability of microprogramming software for processors from Intel, AMD, ARM, and IBM arises from the existence of speculative execution states that can lead to access to already freed memory areas, if the processor mispredicts branch instructions in the code. Exploiting this vulnerability...

kernel: use-after-free in smb2_is_status_io_timeout()

A use-after-free flaw was found in smb2isstatusiotimeout in CIFS in the Linux Kernel. After CIFS transfers response data to a system call, there are still local variable points to the memory region, and if the system call frees it faster than CIFS uses it, CIFS will access a free memory region,...
