UBUNTU-CVE-2023-53231

In the Linux kernel, the following vulnerability has been resolved: erofs: Fix detection of atomic context Current check for atomic context is not sufficient as zerofsdecompressqueueendio can be called under rcu lock from blkmqflushpluglist. See the stacktrace 1 In such case we should hand off th...

CVE-2022-50313

Summary: CVE-2022-50313 affects the Linux kernel (EROF S subsystem). The root cause is that the i_size field is signed; crafted negative i_size can be interpreted as a fast symlink, triggering an order = MAX_ORDER warning. The fix changes the handling to fall back to the generic path for such unu...

CVE-2022-50313 erofs: fix order >= MAX_ORDER warning due to crafted negative i_size

In the Linux kernel, the following vulnerability has been resolved: erofs: fix order = MAXORDER warning due to crafted negative isize As syzbot reported 1, the root cause is that isize field is a signed type, and negative isize is also less than EROFSBLKSIZ. As a consequence, it's handled as fast...

CVE-2023-53231

The CVE-2023-53231 entry concerns the Linux kernel erofs subsystem. The vulnerability stems from incorrect detection of atomic context when z_erofs_decompressqueue_endio can be invoked under an RCU/lock context (e.g., from blk_mq_flush_plug_list). The patch updates the context check to rcu_read_l...
