CVE-2023-53494 (GCVE-0-2023-53494)

Vulnerability from cvelistv5 – Published: 2025-10-01 11:45 – Updated: 2025-10-01 11:45

Title

crypto: xts - Handle EBUSY correctly

Summary

In the Linux kernel, the following vulnerability has been resolved: crypto: xts - Handle EBUSY correctly As it is xts only handles the special return value of EINPROGRESS, which means that in all other cases it will free data related to the request. However, as the caller of xts may specify MAY_BACKLOG, we also need to expect EBUSY and treat it in the same way. Otherwise backlogged requests will trigger a use-after-free.

Severity ?

No CVSS data available.

CVE-2022-50367 (GCVE-0-2022-50367)

Vulnerability from cvelistv5 – Published: 2025-09-17 14:56 – Updated: 2026-01-14 18:42

Title

fs: fix UAF/GPF bug in nilfs_mdt_destroy

Summary

In the Linux kernel, the following vulnerability has been resolved: fs: fix UAF/GPF bug in nilfs_mdt_destroy In alloc_inode, inode_init_always() could return -ENOMEM if security_inode_alloc() fails, which causes inode->i_private uninitialized. Then nilfs_is_metadata_file_inode() returns true and nilfs_free_inode() wrongly calls nilfs_mdt_destroy(), which frees the uninitialized inode->i_private and leads to crashes(e.g., UAF/GPF). Fix this by moving security_inode_alloc just prior to this_cpu_inc(nr_inodes)

Severity ?

7.8 (High)
