GHSA-X35G-752C-R3XH
Vulnerability from github – Published: 2024-07-29 18:30 – Updated: 2025-11-04 00:31In the Linux kernel, the following vulnerability has been resolved:
ata: libata-core: Fix double free on error
If e.g. the ata_port_alloc() call in ata_host_alloc() fails, we will jump to the err_out label, which will call devres_release_group(). devres_release_group() will trigger a call to ata_host_release(). ata_host_release() calls kfree(host), so executing the kfree(host) in ata_host_alloc() will lead to a double free:

GHSA-X73R-R6QR-625X
Vulnerability from github – Published: 2025-10-07 18:31 – Updated: 2026-02-04 18:30In the Linux kernel, the following vulnerability has been resolved:
bpf, sockmap: Fix repeated calls to sock_put() when msg has more_data
In tcp_bpf_send_verdict() redirection, the eval variable is assigned to __SK_REDIRECT after the apply_bytes data is sent, if msg has more_data, sock_put() will be called multiple times.
We should reset the eval variable to __SK_NONE every time more_data starts.
This causes:

GHSA-X88Q-4F25-F826
Vulnerability from github – Published: 2025-05-20 18:30 – Updated: 2025-11-17 18:30In the Linux kernel, the following vulnerability has been resolved:
net_sched: ets: Fix double list add in class with netem as child qdisc
As described in Gerrard's report [1], there are use cases where a netem child qdisc will make the parent qdisc's enqueue callback reentrant. In the case of ets, there won't be a UAF, but the code will add the same classifier to the list twice, which will cause memory corruption.
In addition to checking for qlen being zero, this patch checks whether the class was already added to the active_list (cl_is_active) before doing the addition to cater for the reentrant case.

Mitigation
Choose a language that provides automatic memory management.
Mitigation
Ensure that each allocation is freed only once. After freeing a chunk, set the pointer to NULL to ensure the pointer cannot be freed again. In complicated error conditions, be sure that clean-up routines respect the state of allocation properly. If the language is object oriented, ensure that object destructors delete each chunk of memory only once.
Mitigation
Use a static analysis tool to find double free instances.
