UBUNTU-CVE-2025-39782

In the Linux kernel, the following vulnerability has been resolved: jbd2: prevent softlockup in jbd2logdocheckpoint Both jbd2logdocheckpoint and jbd2journalshrinkcheckpointlist periodically release jlistlock after processing a batch of buffers to avoid long hold times on the jlistlock. However,...

CVE-2025-39782

CVE-2025-39782 concerns the Linux kernel, specifically the JBD2 journal path. The issue arises because jbd2_log_do_checkpoint() and jbd2_journal_shrink_checkpoint_list() contend for j_list_lock, potentially causing long wait times that can trigger softlockups if sleeping calls do not occur. The a...
