glibc: Integer overflow in memalign leads to heap corruption

A flaw was found in the glibc library. Passing an excessively large alignment value to the memalign suite of functions, such as memalign, posixmemalign, alignedalloc, valloc and pvalloc, an integer overflow can occur during internal size calculations due to improper overflow checks, causing an...

Vulnerabilities of functions memalign(), posix_memalign(), aligned_alloc(), valloc(), and pvalloc() in the GNU C Library, which allow attackers to execute arbitrary code, cause system failures, or disclose sensitive information.

The vulnerability of the functions memalign, posixmemalign, alignedalloc, valloc, and pvalloc in the GNU C Library is related to integer overflow. Exploiting this vulnerability can allow an attacker to cause service failures or disclose confidential information...

CVE-2026-0861

A flaw was found in the glibc library. Passing an excessively large alignment value to the memalign suite of functions, such as memalign, posixmemalign, alignedalloc, valloc and pvalloc, an integer overflow can occur during internal size calculations due to improper overflow checks, causing an...

PT-2026-2957

Name of the Vulnerable Software and Affected Versions GNU C Library versions 2.30 through 2.42 Description Providing an excessively large alignment value to the memalign family of functions – including memalign, posix memalign, aligned alloc, valloc, and pvalloc – within the GNU C Library can lea...

CVE-2021-3420

A flaw was found in newlib in versions prior to 4.0.0. Improper overflow validation in the memory allocation functions mEMALIGn, pvALLOc, nanomemalign, nanovalloc, nanopvalloc could case an integer overflow, leading to an allocation of a small buffer and then to a heap-based buffer overflow...

Name of the Vulnerable Software and Affected Versions newlib versions prior to 4.0.0 Description A flaw was found in newlib due to improper overflow validation in memory allocation functions, such as mEMALIGn, pvALLOc, nano memalign, nano valloc, and nano pvalloc. This could cause an integer...

CVE-2021-3420: Integer Overflow or Wraparound

A flaw was found in newlib in versions prior to 4.0.0. Improper overflow validation in the memory allocation functions mEMALIGn, pvALLOc, nanomemalign, nanovalloc, nanopvalloc could case an integer overflow, leading to an allocation of a small buffer and then to a heap-based buffer overflow...

The vulnerabilities of the library that handles system calls and the core functions of glibc allow a perpetrator to cause a service failure.

The multiple vulnerabilities in the malloc/malloc.c file of the library that provides system calls and core functions of glibc are caused by integer overflows. Exploiting these vulnerabilities can allow an attacker to trigger a service failure damage to dynamic memory by specifying an excessively...

glibc: three integer overflows in memory allocator

Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in glibc's memory allocator functions pvalloc, valloc, and memalign. If an application used such a function, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of t...

DEBIAN-CVE-2013-4332

Multiple integer overflows in malloc/malloc.c in the GNU C Library aka glibc or libc6 2.18 and earlier allow context-dependent attackers to cause a denial of service heap corruption via a large value to the 1 pvalloc, 2 valloc, 3 posixmemalign, 4 memalign, or 5 alignedalloc functions...
