AI-suggested
A fix is available that removes the copying of the ISR table in the drm/omap DSI driver to prevent use-after-free conditions. Users should apply the official kernel updates that address this vulnerability. Since this is a kernel-level issue, updating to a patched kernel version is the recommended remediation.
Description
A use-after-free (UAF) vulnerability in the Linux kernel's drm/omap DSI driver was resolved by changing how the interrupt service routine (ISR) table is handled. The vulnerability arises because stack-allocated objects are passed to ISRs, and copying the ISR table allowed unregistering interrupts in a way that could lead to UAF if interrupts were unregistered while being handled. The fix avoids copying the ISR table, mitigating the risk.
