BIT-POSTGRESQL-2026-14669 PostgreSQL to_char heap buffer overflow executes arbitrary code

Heap buffer overflow in PostgreSQL tochartimestamptz allows the party choosing the timezone to execute arbitrary code as the operating system user running the database, via a long POSIX timezone abbreviation. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected...

BIT-POSTGRESQL-2026-14664 PostgreSQL regexp heap buffer overflow executes arbitrary code

Heap buffer overflow in PostgreSQL regexp allows the query author to execute arbitrary code as the operating system user running the database, via text that would not pass encoding validation. This shares heritage with CVE-2026-2006, but this case involved unanticipated data growth when...

BIT-MONGODB-2026-13077 Out-of-Bounds Heap Read in BSON CodeWScope Element Parsing via Malformed BSONColumn Data

A missing bounds check in the BSON CodeWScope element accessors allows an attacker to trigger an out-of-bounds heap read via a crafted aggregation pipeline. The vulnerability can be exploited by an authenticated user by generating a malformed BSONColumn data containing a CodeWScope element,...

AZL-96876 CVE-2026-75900 affecting package swtpm 0.8.1-5

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-2026-58088

The ELF core dump code counted the number of dumpable VM map entries, allocated a buffer for the corresponding program headers, then iterated over the map a second time to populate them. A process sharing the address space via rfork2 can mutate the map between the two passes, causing the second...

CVE-2026-58087

The GETALL and SETALL commands in semctl2 recorded the number of semaphores in the target set, dropped the lock protecting the set, allocated a buffer sized for that count, and reacquired the lock. A sequence-number check was used to verify that the set had not been replaced in the interim, but t...

CVE-2026-58088 Race condition in ELF core dump segment counting

The ELF core dump code counted the number of dumpable VM map entries, allocated a buffer for the corresponding program headers, then iterated over the map a second time to populate them. A process sharing the address space via rfork2 can mutate the map between the two passes, causing the second...

CVE-2026-58088

Affected: All supported FreeBSD versions. Root cause: A race condition in ELF core dump code — a second-pass write to the program-header buffer is not bounds-checked against the count from the first pass, so a process sharing the address space via rfork(2) can mutate the VM map between passes. Im...

CVE-2026-58087 Heap out-of-bounds access in semctl(2)

The GETALL and SETALL commands in semctl2 recorded the number of semaphores in the target set, dropped the lock protecting the set, allocated a buffer sized for that count, and reacquired the lock. A sequence-number check was used to verify that the set had not been replaced in the interim, but t...

CVE-2026-58087

CVE-2026-58087 is a heap out-of-bounds access in the GETALL and SETALL commands of FreeBSD's semctl(2) system call. The root cause is a sequence-number wrap after 0x8000 create/destroy cycles: an unprivileged local user can rapidly destroy and recreate semaphore sets at the same index, causing a ...

CVE-2026-75900 Swtpm: swtpm: out-of-bounds read in swtpm_nvram_checkheader due to sizeof(pointer) vs sizeof(struct) mismatch

An out-of-bounds read vulnerability was found in swtpm's SWTPMNVRAMCheckHeader function.

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...

CVE-2026-58081 Heap based buffer overflow in iconv(3)

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. An application that uses iconv3 to convert untrusted input to or from one of the affected encodings may be vulnerable to buffer...

CVE-2026-49429

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. A local user with the "userused" delegated ZFS permission can trigger a kernel he...
