Affected versions of this package are vulnerable to CRLF Injection due to improperly validating user input specifically carriage return and line feed bytes within the Symfony\Component\Mime\Address constructor. The constructor accept...

CVE-2026-5947 SIG(0) validation during query flood may lead to undefined behavior

Undefined behavior may result due to a race condition leading to a use-after-free violation. If BIND receives an incoming DNS message signed with SIG0, it begins work to validate that signature. If, during that validation, the "recursive-clients" limit is reached as would occur during a query...

CVE-2026-3039

CVE-2026-3039 affects BIND 9.x when TKEY-based authentication via GSS-API tokens is used; the issue is a memory-exhaustion vulnerability triggered by malicious packets in Active Directory/Kerberos DNS setups. Affected versions span 9.0.0–9.16.50, 9.18.0–9.18.48, 9.20.0–9.20.22, 9.21.0–9.21.21, pl...

kernel: "Fragnesia" is a variant of Dirty Frag vulnerability in the ESP/XFRM leading to Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's XFRM ESP-in-TCP subsystem. Unsafe in-place cryptographic processing allows a low-privileged local attacker to write arbitrary bytes into the page cache of read-only files, including sensitive system files. An attacker can exploit this to overwrite privileged...
