Vulnerability from github – Published: 2022-11-02 18:10 – Updated: 2022-11-02 18:10
VLAI
Summary
Unchecked Return Value to NULL Pointer Dereference in PDFDocumentHandler.cpp
Details

Impact

The package muhammara before 2.6.0; all versions of package hummus are vulnerable to Denial of Service (DoS) when supplied with a maliciously crafted PDF file to be appended to another.

Patches

It has been patched in 2.6.0 for muhammara and not at all for hummus

Workarounds

Do not process files from untrusted sources

References

PR: https://github.com/julianhille/MuhammaraJS/pull/194 Issue: https://github.com/julianhille/MuhammaraJS/issues/191 Issue in hummus: https://github.com/galkahana/HummusJS/issues/293

Outline differences to https://nvd.nist.gov/vuln/detail/CVE-2022-25892

The difference is one is in src/deps/PDFWriter/PDFParser.cpp and the other is PDFDocumentHandler.cpp both is a null pointer but for different cases These are totally diffent issues, one is in reading a pdf the other is in appendending a maliciously crafted one. The function calls are different the versions in which they are solved are diffent.

Details

In the Linux kernel, the following vulnerability has been resolved:

drm/amdkfd: debugfs hang_hws skip GPU with MES

debugfs hang_hws is used by GPU reset test with HWS, for MES this crash the kernel with NULL pointer access because dqm->packet_mgr is not setup for MES path.

Skip GPU with MES for now, MES hang_hws debugfs interface will be supported later.

GHSA-RF58-PP6R-5653

Vulnerability from github – Published: 2024-10-21 18:30 – Updated: 2025-11-04 00:31
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

gso: fix udp gso fraglist segmentation after pull from frag_list

Detect gso fraglist skbs with corrupted geometry (see below) and pass these to skb_segment instead of skb_segment_list, as the first can segment them correctly.

Valid SKB_GSO_FRAGLIST skbs - consist of two or more segments - the head_skb holds the protocol headers plus first gso_size - one or more frag_list skbs hold exactly one segment - all but the last must be gso_size

Optional datapath hooks such as NAT and BPF (bpf_skb_pull_data) can modify these skbs, breaking these invariants.

In extreme cases they pull all data into skb linear. For UDP, this causes a NULL ptr deref in __udpv4_gso_segment_list_csum at udp_hdr(seg->next)->dest.

Detect invalid geometry due to pull, by checking head_skb size. Don't just drop, as this may blackhole a destination. Convert to be able to pass to regular skb_segment.

Vulnerability from github – Published: 2024-12-27 15:31 – Updated: 2025-01-07 18:30

Details

In the Linux kernel, the following vulnerability has been resolved:

erofs: fix file-backed mounts over FUSE

syzbot reported a null-ptr-deref in fuse_read_args_fill: fuse_read_folio+0xb0/0x100 fs/fuse/file.c:905 filemap_read_folio+0xc6/0x2a0 mm/filemap.c:2367 do_read_cache_folio+0x263/0x5c0 mm/filemap.c:3825 read_mapping_folio include/linux/pagemap.h:1011 [inline] erofs_bread+0x34d/0x7e0 fs/erofs/data.c:41 erofs_read_superblock fs/erofs/super.c:281 [inline] erofs_fc_fill_super+0x2b9/0x2500 fs/erofs/super.c:625

Unlike most filesystems, some network filesystems and FUSE need unavoidable valid file pointers for their read I/Os [1]. Anyway, those use cases need to be supported too.

Details

A null pointer dereference vulnerability exists in airpig2011 IEC104 thru Commit be6d841 (2019-07-08). When multiple threads enqueue elements concurrently via IEC10X_PrioEnQueue, the function may dereference a null or freed queue pointer, resulting in a segmentation fault and potential denial-of-service.

Mitigation MIT-56
Implementation

For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].

Mitigation
Requirements

Select a programming language that is not susceptible to these issues.

Mitigation
Implementation

Check the results of all functions that return a value and verify that the value is non-null before acting upon it.

Mitigation
Architecture and Design

Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.

Mitigation
Implementation

Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
