Description

In the Linux kernel, the following vulnerability has been resolved: cifs: potential buffer overflow in handling symlinks Smatch printed a warning: arch/x86/crypto/poly1305_glue.c:198 poly1305_update_arch() error: __memcpy() 'dctx->buf' too small (16 vs u32max) It's caused because Smatch marks 'link_len' as untrusted since it comes from sscanf(). Add a check to ensure that 'link_len' is not larger than the size of the 'link_str' buffer.

Affected configurations

• linux linux kernel (>= 2.6.37 < 4.9.311) • linux linux kernel (>= 4.10 < 4.14.276) • linux linux kernel (>= 4.15 < 4.19.239) • linux linux kernel (>= 4.20 < 5.4.190) • linux linux kernel (>= 5.5 < 5.10.112) • linux linux kernel (>= 5.11 < 5.15.35) • linux linux kernel (>= 5.16 < 5.17.4) • linux linux kernel 5.18
