encoding/asn1: Parsing DER payload can cause memory exhaustion in encoding/asn1

A memory exhaustion flaw has been discovered in the golang encoding/asn1 module. Within parseSequenceOf, reflect.MakeSlice is being used to pre-allocate a slice that is needed in order to fully validate the given DER payload. The size of the slice allocated are also multiple times larger than the...

ROS-20260317-73-0007

A vulnerability in the maspreallocate function of the lib/mapletree.c module of the Linux kernel is related to pointer dereferencing resulting from incorrect memory allocation. Exploitation of the vulnerability may allow an attacker to cause a denial of service...

maple_tree: fix MA_STATE_PREALLOC flag in mas_preallocate()

...

The vulnerability of the `snd_pcm_lib_preallocate_proc_write()` function in the `sound/core/pcm_memory.c` module, which is part of Linux’s kernel-based audio card support mechanism, allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the sndpcmlibpreallocateprocwrite function in the sound/core/pcmmemory.c module, which is part of Linux’s audio card support, relates to the reallocation of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality,...

RUSTSEC-2019-0007 Processing of maliciously crafted length fields causes memory allocation SIGABRTs

Affected versions of this crate tried to preallocate a vector for an arbitrary amount of bytes announced by the ASN.1-DER length field without further checks. This allows an attacker to trigger a SIGABRT by creating length fields that announce more bytes than the allocator can provide. The flaw w...
