Privilege escalation when similar master and non-master passdbs are used
CVE: CVE-2022-30550
Component: dovecot
CWE: CWE-284
Severity: Moderate
CVSS v3: 7.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N
Release date: 2022-07-06T00:00:00+00:00

A vulnerability was found in the Dovecot IMAP Server. When two passdb configuration entries exist in the Dovecot configuration, which have the same driver and args settings, the incorrect username_filter and mechanism settings can be applied to passdb definitions. These incorrect settings can lead to an unintended security configuration and can permit privilege escalation with certain configurations involving a master user authentication. If the same passwd file or PAM is used for both normal and master users, an attacker could easily become a master user, potentially escalating privileges on the system.


Remediation:
Always authenticate master users from a different source than regular users, for example, use a separate passwd file. Alternatively, you can use global ACLs to ensure that only legitimate master users have privileged access.
Specially crafted HTTP request can trigger an uncaught exception

net: ethernet: ti: Fix return type of netcp_ndo_start_xmit()
CVE: CVE-2022-50486
Component: kernel
CWE: CWE-843
Severity: Moderate
CVSS v3: 4.7/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H
Release date: 2022-01-01T00:00:00+00:00

A type confusion flaw was found in the Linux kernel's Texas Instruments NETCP Ethernet driver in the packet transmit function signature. 
A local user can trigger this issue on systems with kernel Control Flow Integrity enabled, where the incorrect return type of the ndo_start_xmit function causes CFI validation failures during indirect function calls. This results in either a kernel panic or thread termination, leading to denial of service.

Statement: The netcp_ndo_start_xmit function is declared with a return type of 'int' instead of the expected 'netdev_tx_t' enum. When CONFIG_CFI_CLANG is enabled, the kernel validates indirect function call targets against their expected prototypes to prevent control-flow hijacking attacks. The type mismatch causes CFI to reject the call, triggering either a kernel panic or killing the calling thread. This only affects systems compiled with Clang's CFI support enabled and running on Texas Instruments NETCP hardware. Without CFI enabled, the incorrect return type is harmless due to ABI compatibility between int and the enum.

staging: rtl8723bs: fix potential memory leak in rtw_init_drv_sw()
CVE: CVE-2022-50469
Component: kernel
Severity: None
Release date: 2022-01-01T00:00:00+00:00

In the Linux kernel, the following vulnerability has been resolved:

staging: rtl8723bs: fix potential memory leak in rtw_init_drv_sw()

In rtw_init_drv_sw(), there are various init functions are called to
populate the padapter structure and some checks for their return value.
However, except for the first one error path, the other five error paths
do not properly release the previous allocated resources, which leads to
various memory leaks.

This patch fixes them and keeps the success and error separate.
Note that these changes keep the form of `rtw_init_drv_sw()` in
"drivers/staging/r8188eu/os_dep/os_intfs.c". As there is no proper device
to test with, no runtime testing was performed.

erofs: wake up all waiters after z_erofs_lzma_head ready
CVE: CVE-2022-50193
Component: kernel
Severity: None
Release date: 2022-01-01T00:00:00+00:00

In the Linux kernel, the following vulnerability has been resolved:

erofs: wake up all waiters after z_erofs_lzma_head ready

When the user mounts the erofs second times, the decompression thread
may hung. The problem happens due to a sequence of steps like the
following:

1) Task A called z_erofs_load_lzma_config which obtain all of the node
   from the z_erofs_lzma_head.

2) At this time, task B called the z_erofs_lzma_decompress and wanted to
   get a node. But the z_erofs_lzma_head was empty, the Task B had to
   sleep.

3) Task A release nodes and push nodes into the z_erofs_lzma_head. But
   task B was still sleeping.

One example report when the hung happens:

Component: kernel
CWE: CWE-401
Severity: Low
CVSS v3: 5.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H
Release date: 2022-01-01T00:00:00+00:00

In the Linux kernel, the following vulnerability has been resolved:

tracing/histograms: Fix memory leak problem

This reverts commit 46bbe5c671e06f070428b9be142cc4ee5cedebac.

As commit 46bbe5c671e0 ("tracing: fix double free") said, the
"double free" problem reported by clang static analyzer is:
  > In parse_var_defs() if there is a problem allocating
  > var_defs.expr, the earlier var_defs.name is freed.
  > This free is duplicated by free_var_defs() which frees
  > the rest of the list.

However, if there is a problem allocating N-th var_defs.expr:
  + in parse_var_defs(), the freed 'earlier var_defs.name' is
    actually the N-th var_defs.name;
  + then in free_var_defs(), the names from 0th to (N-1)-th are freed;

                        IF ALLOCATING PROBLEM HAPPENED HERE!!! -+
                                                                 \
                                                                  |
          0th           1th                 (N-1)-th      N-th    V
          +-------------+-------------+-----+-------------+-----------
var_defs: | name | expr | name | expr | ... | name | expr | name | ///
          +-------------+-------------+-----+-------------+-----------

These two frees don't act on same name, so there was no "double free"
problem before. Conversely, after that commit, we get a "memory leak"
problem because the above "N-th var_defs.name" is not freed.

If enable CONFIG_DEBUG_KMEMLEAK and inject a fault at where the N-th
var_defs.expr allocated, then execute on shell like:
  $ echo 'hist:key=call_site:val=$v1,$v2:v1=bytes_req,v2=bytes_alloc' > \
/sys/kernel/debug/tracing/events/kmem/kmalloc/trigger

Then kmemleak reports:

In the Linux kernel, the following vulnerability has been resolved:

stmmac: intel: Add a missing clk_disable_unprepare() call in intel_eth_pci_remove()

Commit 09f012e64e4b ("stmmac: intel: Fix clock handling on error and remove
paths") removed this clk_disable_unprepare()

This was partly revert by commit ac322f86b56c ("net: stmmac: Fix clock
handling on remove path") which removed this clk_disable_unprepare()
because:
"
   While unloading the dwmac-intel driver, clk_disable_unprepare() is
   being called twice in stmmac_dvr_remove() and
   intel_eth_pci_remove(). This causes kernel panic on the second call.
"

However later on, commit 5ec55823438e8 ("net: stmmac: add clocks management
for gmac driver") has updated stmmac_dvr_remove() which do not call
clk_disable_unprepare() anymore.

So this call should now be called from intel_eth_pci_remove().
