The gawk package is the GNU implementation of awk. The awk utility interprets a special-purpose programming language that makes it possible to handle simple data-reformatting jobs with just a few lines of code. Security Fix(es):

Use After Free vulnerability has been found in "io.c" program file of gawk (do_getline_redir() routine). This issue may lead to a crash. It affects gawk in versions 5.4.0 and below.(CVE-2026-40467)

Integer overflow vulnerability has been found in "builtin.c" program file of gawk. This issue may lead to memory exhaustion on the hosting operating system and could be used to overwrite gawk heap metadata and objects with attacker-controlled bytes. It affects gawk in versions 5.4.0 and below.(CVE-2026-40468)

Integer overflow vulnerability has been found in "builtin.c" program file of gawk (do_sub() routine). This issue could be used to overwrite gawk heap metadata and objects causing the program to crash. It affects 32-bit builds of gawk in versions 5.4.0 and below.(CVE-2026-40469)

Buffer overflow vulnerability has been found in "extension/readdir.c" program file of gawk (ftype() routine). This issue could be used to crash the program and potentially to achieve code execution, although the latter has not been confirmed to be feasible. It affects gawk in versions 5.4.0 and below.(CVE-2026-40553)

gawk: gawk: Denial of Service due to Use After Free vulnerability in io.c gawk: gawk: Memory corruption via integer overflow gawk: gawk: Denial of Service due to integer overflow gawk: Gawk: Buffer overflow in ftype() routine may lead to code execution or denial of service
