GHSA-F9F8-9PMF-XV68
Vulnerability from github – Published: 2025-08-14 00:05 – Updated: 2025-08-14 17:15A Helm contributor discovered an improper validation of type error when parsing Chart.yaml and index.yaml files that can lead to a panic.
Impact
There are two areas of YAML validation that were impacted. First, when a Chart.yaml file had a null maintainer or the child or parent of a dependencies import-values could be parsed as something other than a string, helm lint would panic. Second, when an index.yaml had an empty entry in the list of chart versions Helm would panic on interactions with that repository.
Patches
This issue has been resolved in Helm v3.18.5.
Workarounds
Ensure YAML files are formatted as Helm expects prior to processing them with Helm.
References
Helm's security policy is spelled out in detail in our SECURITY document.

Vulnerability from github – Published: 2024-11-19 18:31 – Updated: 2025-11-04 00:32In the Linux kernel, the following vulnerability has been resolved:
nfs: Fix KMSAN warning in decode_getfattr_attrs()

The KMSAN warning is triggered in decode_getfattr_attrs(), when calling decode_attr_mdsthreshold(). It appears that fattr->mdsthreshold is not initialized.
Fix the issue by initializing fattr->mdsthreshold to NULL in nfs_fattr_init().

GHSA-FCJF-98WX-3V8X
Vulnerability from github – Published: 2024-08-17 09:30 – Updated: 2026-05-12 12:32In the Linux kernel, the following vulnerability has been resolved:
sysctl: always initialize i_uid/i_gid
Always initialize i_uid/i_gid inside the sysfs core so set_ownership() can safely skip setting them.
Commit 5ec27ec735ba ("fs/proc/proc_sysctl.c: fix the default values of i_uid/i_gid on /proc/sys inodes.") added defaults for i_uid/i_gid when set_ownership() was not implemented. It also missed adjusting net_ctl_set_ownership() to use the same default values in case the computation of a better value failed.

Mitigation
Explicitly initialize the resource before use. If this is performed through an API function or standard procedure, follow all required steps.
Mitigation
Pay close attention to complex conditionals that affect initialization, since some branches might not perform the initialization.
Mitigation
Avoid race conditions (CWE-362) during initialization routines.
Mitigation
Run or compile the product with settings that generate warnings about uninitialized variables or data.
No CAPEC attack patterns related to this CWE.
