CVE-2019-17666 [HIGH] CWE-120 GHSA-wcxr-pc79-vh4x: rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps
rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel through 5.3.6 lacks a certain upper-bound check, leading to a buffer overflow.

kernel_security·2021-04-20
CVE-2019-0145 fortify: Detect struct member overflows in memcpy() at compile-time
fortify: Detect struct member overflows in memcpy() at compile-time
memcpy() is dead; long live memcpy()
tl;dr: In order to eliminate a large class of common buffer overflow
flaws that continue to persist in the kernel, have memcpy() (under
CONFIG_FORTIFY_SOURCE) perform bounds checking of the destination struct
member when they have a known size. This would have caught all of the
memcpy()-related buffer write overflow flaws identified in at least the
last three years.
Background and analysis:
While stack-based buffer overflow flaws are largely mitigated by stack
canaries (and similar) features, heap-based buffer overflow flaws continue
to regularly appear in the kernel. Many classes of heap buffer overflows
are mitigated by FORTIFY_SOURCE when using the strcpy() family of
functions, b
