CVE-2026-18238 OOBR in rpcap client in libpcap before 1.10.7

The rpcap client code that processes a RPCAPMSGPACKET message received from the server incorrectly validates its headers. A malicious server can send a crafted message and cause the client to treat up to 20 bytes of the client process memory beyond the end of the buffer as if it was a part of the...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ksmbd: The validation of the request buffer size was added in smb2allocaterspbuf. The response buffer should be allocated in smb2allocaterspbuf before validation of the request. However, fields within the payload as well as the...

Astra Linux – Vulnerability found in Linux 5.15, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: Fix SKB corruption in REO destination ring While running traffics for a long time, randomly an RX descriptor filled with value "0" from REO destination ring is received. This descriptor which is invalid causes the...

CVE-2026-75900

An out-of-bounds read vulnerability was found in swtpm's SWTPMNVRAMCheckHeader function. The entry guard checks the buffer length against sizeofbh, where bh is a pointer, instead of sizeofbh, the actual struct size. This allows an undersized buffer to pass validation, causing a 2-byte heap overre...

CVE-2026-75900

swtpm's SWTPM_NVRAM_CheckHeader() validates buffer length against sizeof(pointer) instead of sizeof(struct), allowing an undersized buffer to pass and cause a 2-byte heap overread (6 bytes on 32-bit). Impact: daemon termination and heap data leakage to logs. Red Hat reports no mitigation; fixed i...
