mailpit -- WebSocket origin check bypass via percent-encoded path

Mailpit author reports: The cross-site WebSocket hijacking fix was reimplemented as an origin check gated on a raw-URI prefix test, but Go's ServeMux routes on the percent-decoded path, so requesting /%61pi/events reaches the WebSocket handler while skipping the only origin control, and the...

FreeBSD -- Incorrect audit records for ptrace(2) syscall requests

Problem Description: When auditing a system call executed via ptracePTSCREMOTE, the kernel passed the return value of an internal setup function to AUDITSYSCALLEXIT rather than the actual result of the executed system call. As a result, committed audit records for system calls which returned an...

FreeBSD -- Buffer overflow in libalias RTSP handler

Problem Description: The RTSP handler in libalias rewrote outgoing packets into a fixed-length stack buffer without checking whether the rewritten data fit in the buffer, or whether the result fit back in the original packet. Impact: A host sending crafted RTSP traffic from inside a NAT gateway...

FreeBSD -- Jail reference count underflow

Problem Description: When the JAILATDESC flag is specified, kernjailset and kernjailget released the reference to the caller's current prison before looking up the jail descriptor. If the descriptor lookup failed, error-handling paths released the same reference a second time. Impact: An...

FreeBSD-kernel -- Kernel stack disclosure in 32-bit compatibility support

Problem Description: The compat32 kevent handler translates a 64-bit kevent struct into a stack- declared 32-bit struct. It did not first zero the stack struct. Impact: An unprivileged user may observe a small amount of uninitialized kernel stack data, which may contain sensitive information...

FreeBSD -- Multiple vulnerabilities in iconv(3)

Problem Description: Several encoding modules, including HZ, UTF-7, VIQR, and ZW, did not properly check the size of the caller-supplied output buffer before writing converted characters. CVE-2026-58081 The ISO-2022 encoding module used a stack buffer sized to MBLENMAX 6 bytes for intermediate...

FreeBSD -- Use-after-free in TCP RACK stack option handler

Problem Description: The RACK setsockopt2 handler drops the connection lock in order to copy option data from userspace, then reacquires the lock. After reacquiring, it verifies that the TCP stack had not been switched away, but did not reload its pointer to the stack's per-connection control...

FreeBSD -- Multiple vulnerabilities in POSIX largepage objects

Problem Description: Pages belonging to largepage shared memory objects were not explicitly wired. When sendfile2 transmitted such an object with the SFNOCACHE flag, it freed the underlying pages after transmission even though existing mappings still referred to them. CVE-2026-49427 Separately,...

FreeBSD -- Use-after-free in device pager page list

Problem Description: When msyncMSINVALIDATE is called on a mapping of an unmanaged device object, the physical pages in the mapping range are marked invalid but remain in the pager's page list. A subsequent page fault will cause the fault handler to re-insert the page into the object's list. This...

FreeBSD -- Multiple vulnerabilities in OpenZFS

Problem Description: The ZFSIOCUSERSPACEMANY ioctl, used by zfs-userspace8, truncated a 64-bit output buffer size to a 32-bit integer for the kernel allocation, but used the original 64-bit size as the buffer limit when writing records. The ZFSIOCRECVNEW ioctl, in the heal receive path, similarly...

FreeBSD -- Kernel stack disclosure in Linux compatibility layer

Problem Description: The Linux waitid implementation translates a FreeBSD siginfot struct into a stack-declared Linux siginfot. It did not first zero the stack struct. Impact: An unprivileged user may observe 104 bytes of uninitialized kernel stack data, which may contain sensitive information...

FreeBSD -- unlinkat(2) ignores AT_RESOLVE_BENEATH flag

Problem Description: The kernel function that implements unlinkat2 and funlinkat2 validated the ATRESOLVEBENEATH flag but failed to pass it through to the underlying path lookup. The flag was silently dropped, so path resolution was not actually restricted. Impact: A process that uses...

FreeBSD -- Local privilege escalation via execve(2) TOCTOU race

Problem Description: During execve2 of a SUID binary, the new virtual address space is installed before the process credentials are updated. During this window, a process running as the same user can access the target process's memory via procfs or linprocfs, because the kernel's debugging...

PostgresSQL JDBC -- Silent channel-binding authentication downgrade via unsupported certificate algorithms

PostgreSQL project reports: channelBinding=require connections can be silently downgraded from SCRAM-SHA-256-PLUS with channel binding to plain SCRAM-SHA-256 without it, losing the man-in-the-middle protection the setting is meant to guarantee. An attacker who can intercept the TLS connection...

FreeBSD -- Remote DOS via uninitialized memory access in KTLS receive

Problem Description: When building the iovec array for a received TLS 1.2 CBC record, ktlsocftlscbcdecrypt incremented the iovec index for every mbuf in the chain, including mbufs that were skipped because they contained only TLS header bytes. This left uninitialized entries in the iovec array. T...
